For a Chicago-based arts nonprofit, I’d put portal architecture + nonprofit CRM/membership expertise ahead of pure visual/web-design credentials. A membership portal can quickly become a CRM, payments, events, member directory, donations, and permissions project—not just a website. Chicago Loop Alliance’s recent RFP is a useful illustration of how broad these requirements can become. Loop Chicago Loop Chicago

Firms I’d approach

1. Heller Consulting — CRM/technology strategy

• Chicago-based and focused on nonprofit technology, including Salesforce and Microsoft Dynamics.
• Particularly worth approaching if you need to decide what the underlying CRM/technology stack should be before building the portal.
• Their work includes technology-roadmap and platform-selection engagements for nonprofits.
• BSCI — membership/association systems

• Chicago firm specifically oriented toward member-based organizations and nonprofits.
• Strong candidate if the portal needs membership management, database/CRM integration, billing, events, reporting, and an existing association-management platform such as iMIS.
• Sandstorm Design — UX + portal experience

• Chicago digital-experience agency with work across nonprofits and membership organizations.
• Particularly interesting if you want the portal to feel excellent for members, not merely functional. Their capabilities include UX, accessibility, digital products, and membership/association work.
• LimeRed Studio, Inc. — nonprofit design + web integration

• Chicago agency focused on purpose-driven organizations.
• Their capabilities include UX/UI, WordPress, accessibility, CRM/forms/payments integrations, training, and ongoing maintenance.
• Neoteric Design — custom software/product development

• I'd include them if you're contemplating a genuinely custom portal rather than configuring an off-the-shelf membership system.
• Their focus is web applications and long-lived, maintainable digital products, including work for mission-driven organizations.
• Mightybytes — mission-driven digital/product work

• Chicago agency combining web design, software/product development, and digital strategy.
• Worth an RFP invitation if accessibility, sustainability, governance, and a collaborative nonprofit relationship matter to you.
• Dialogue Theory — brand + digital experience

• Chicago-based strategic design/digital-experience studio with a mission-driven and nonprofit orientation.
• More attractive if the portal is also part of a broader website/member-experience redesign.
• Thirdwave — technical web/portal development

• Chicago digital product/web-development firm with experience across WordPress, Drupal and Liferay.
• A useful candidate when the project has substantial technical/CMS requirements rather than being primarily a marketing-site redesign.

One important alternative: don't necessarily custom-build it

Before hiring an agency to build everything from scratch, I'd also investigate whether your requirements can be met by configuring a nonprofit membership/CRM platform and having an agency customize the front end.

For example, Neon One supports nonprofit CRM, memberships, events and donor-related functionality, and Chicago Cultural Alliance is among its documented nonprofit customers. Featured Customers Soapbox Engage can also expose CRM-powered member directories and resources from Salesforce or Microsoft Dynamics. Soapbox Engage

There are also newer, simpler approaches such as Belong CRM, which is explicitly aimed at nonprofit membership management, and Softr, which offers configurable portals/CRMs for arts organizations. Belong Here Softr

My suggested RFP shortlist

If I were putting together a 5-firm RFP, I'd deliberately get different approaches rather than five similar agencies:

• Heller Consulting — CRM/technology architecture
• BSCI — membership-system expertise
• Sandstorm Design — member UX + digital experience
• LimeRed Studio — nonprofit website + integrations
• Neoteric Design — custom application development

That gives you a useful comparison between buy/configure, integrate, and custom-build approaches.

I'd also make the RFP explicitly ask each firm to address membership tiers/renewals, member self-service, payments, event registration, member directory, private content/resources, staff administration, CRM integration, accessibility, data migration, SSO, security, analytics, and post-launch support. Those are the areas that tend to turn a seemingly simple "membership portal" into a much larger project. Chicago Loop Alliance's recent requirements are a particularly good checklist. Loop Chicago Loop Chicago

If you tell me (1) your approximate membership size, (2) what CRM/membership system you use today, (3) your budget range, and (4) what members need to do inside the portal, I can narrow this to 3–4 firms and give you a side-by-side RFP shortlist with relevant past arts/nonprofit work, likely fit, and questions to ask each one.

Yes. For a Chicago arts nonprofit, I’d put together an initial shortlist that deliberately mixes firms with arts/cultural experience, nonprofit experience, and actual membership/portal/integration expertise.

Firms I’d approach

• Adage Technologies — probably the first firm I’d contact. They are Chicago-based and specifically list both arts/culture/entertainment and associations/membership organizations as core sectors. Their work includes custom web applications and integrations with CRM, AMS, ticketing and other systems. Clutch also identifies a project involving web development and UX/UI for a performing-arts nonprofit. Clutch
• Thirdwave — A Chicago digital product/web-development firm with experience in technically sophisticated sites and portals, including WordPress, Drupal and Liferay. I'd consider them if your portal has significant custom functionality or integrations rather than simply being a membership plugin bolted onto a website.
• Mightybytes — A Chicago agency with nonprofit experience spanning strategy, web/product development, accessibility and training. They could be particularly interesting if the portal needs to be easy for a relatively small nonprofit staff to manage after launch.
• LimeRed Studio, Inc. — Chicago-based and strongly nonprofit-oriented, with web development, UX, accessibility, CRM/forms/payment integrations, training and ongoing support. I'd include them if brand, audience experience and accessibility are as important as the underlying technology.
• Venture Industries Online — Worth a serious conversation specifically because of their arts-organization track record. They cite work for the League of Chicago Theatres and describe building complex sites for member theatres, patrons, artists and administrators. Venture Industries Online
• 83/Creative — Particularly relevant if this is fundamentally a membership portal/web application project. They explicitly specialize in nonprofits and associations and offer member portals, web applications and CRM/AMS integrations, with WordPress and Drupal expertise. 83 Creative
• Three Hive Design — A smaller option worth considering if your needs fit WordPress. They specifically build membership websites with subscription management, gated content and member portals, and also identify artists and cultural institutions among their clients. Three Hive Design
• View Marketing & Creative — Especially interesting if you want a highly polished arts/nonprofit front end while retaining an existing membership platform. They have documented Chicago nonprofit work integrating and visually styling membership software such as MemberClicks, WildApricot and YourMembership. View Marketing

How I'd narrow the RFP

I wouldn't select an agency based primarily on "best Chicago web designer." A membership portal can become a CRM/AMS + payments + events + website + authentication project surprisingly quickly.

I'd send an RFP to 5 firms:

1. Adage Technologies — arts + membership + complex integrations
2. Venture Industries Online — arts-sector specialization
3. 83/Creative — membership portal/web-app specialization
4. LimeRed Studio — nonprofit UX/accessibility + integrations
5. Thirdwave — custom portal/integration capability

Then ask each to respond to exactly the same requirements.

The requirements I'd put in the RFP

At minimum, spell out whether you need:

• Member registration and login
• Individual and/or organizational memberships
• Membership levels and benefits
• Online dues/payment processing
• Automatic renewals and reminders
• Member profiles
• Member directory with privacy controls
• Gated content/resources
• Event registration and member pricing
• Discount/promo codes
• Staff/admin dashboard
• Email/marketing integration
• CRM integration
• Ticketing integration, if applicable
• SSO or integration with your existing website
• Data migration from the existing membership database
• Accessibility/WCAG compliance
• Mobile experience
• Analytics
• Member self-service
• Role-based permissions
• API/integration requirements
• Hosting, security, backups and ongoing maintenance

I'd also require a live demonstration of a comparable membership portal, rather than accepting screenshots of websites.

One useful benchmark: the Chicago Cultural Alliance's current member portal includes organizational accounts, multiple staff users, event submission and member resources, while Chicago Women in Philanthropy's system includes profiles, invoices, event/program registration and member-only resources. Those are good examples of the sort of functionality you may want to distinguish in the RFP. Chicago Cultural Alliance Chicago Women in Philanthropy

If you tell me (1) approximate number of members, (2) current website/CMS, (3) current membership/CRM software, (4) what the portal needs to do, and (5) rough budget, I can turn this into a shortlist of 3–5 agencies with estimated project fit, relevant comparable projects, likely budget range, and the questions I'd ask each one.

For a Chicago-based arts nonprofit, I’d look for an agency that understands membership workflows (tiers, renewals, benefits, member directories, events, donations, CRM/email integrations) rather than just a website redesign shop. A good shortlist to approach:

I’d put these 3 at the top of the outreach list

1. Adage Technologies — especially if you’re a museum, performing arts group, gallery, arts council, or cultural institution and need integrations with systems like ticketing, CRM, or donor databases. Clutch Built In Chicago
2. Orbit Media Studios — if you need a portal plus a major website/content overhaul and want strong nonprofit communications experience. Orbit Media Studios
3. Mightybytes — if you want a smaller team with nonprofit-oriented values and a more hands-on relationship. Clutch

Before you request proposals, define these portal requirements

Agencies will price very differently depending on whether you need:

• Member signup, login, profiles, and renewals
• Membership tiers and pricing rules
• Member directory (public or private)
• Event registration
• Member-only content/resources
• Donation integration
• Email automation (welcome, renewal reminders, campaigns)
• CRM integration (Salesforce, Blackbaud, HubSpot, Neon One, Tessitura, etc.)
• Payment processing
• Staff/admin dashboard
• Accessibility compliance (WCAG)
• Data migration from your current system

Suggested RFP question

Ask each agency:

“Please describe a membership portal you have built or supported, including authentication, payments, CRM integrations, member data management, and ongoing maintenance.”

That question will quickly separate firms that build true member systems from firms that mainly build public-facing websites.

I’d also ask whether they recommend building custom functionality or using an established membership platform (for example, WordPress + membership tools, a CRM-based portal, or a custom application). The right answer depends heavily on your membership size, complexity, and budget.

Yes. For a Chicago arts nonprofit, I’d focus less on generic web-design shops and more on firms that understand membership systems, nonprofit/arts audiences, CRM integrations, events, payments, and member-only content.

My shortlist would be:

1. Adage Technologies — strongest overall fit

• Chicago-based and specifically works across arts/culture/entertainment and associations/membership organizations.
• Particularly attractive if the portal needs custom functionality, integrations with your CRM/AMS, ticketing, events, or other back-office systems.
• They do substantially more than a standard WordPress site: custom applications, backend engineering, CMS/DXP work and integrations.
• I would put them at the top of the RFP list.
• Thirdwave — strong portal/digital-platform candidate

• Chicago digital product and web-development firm with experience building technically sophisticated portals and integration-heavy platforms.
• Their capabilities include WordPress, Drupal and Liferay, plus ongoing hosting/support.
• A good choice if the membership portal is really a digital product, rather than simply a members-only section of your website.
• Sandstorm Design — good for strategy + UX + accessibility

• Chicago agency with experience in nonprofits and membership organizations, as well as substantial web development.
• They work with Drupal, WordPress, Acquia and other enterprise CMS platforms, and explicitly highlight accessibility/governance considerations.
• I'd consider them particularly if the project involves rethinking the member experience and public-facing site together.
• Digital Mountaineers — nonprofit-oriented alternative

• Their positioning is explicitly around cause-driven organizations, with website design/development, UX, analytics, content strategy and digital communications.
• They emphasize working within nonprofit budget constraints and have nonprofit client experience. Digital Mountaineers
• Better fit if you want a smaller, nonprofit-specialist partner rather than a larger technical shop.
• Flamingo Agency — potentially good for a smaller-budget project

• Chicago nonprofit web-design agency focused on WordPress.
• They specifically say they can integrate membership platforms, events and member-only sections, along with donations and email systems. Flamingo Agency
• Their published typical website range is $4,000–$10,000, although a genuinely custom portal would likely be above that. Flamingo Agency

One important distinction

I'd decide first whether you actually need an agency to build a membership system, or an agency to implement/customize an existing membership platform.

For example, Chicago organizations already use fairly sophisticated member portals. The Chicago Cultural Alliance's portal provides member login, event submission and member resources, while Chicago Women in Philanthropy's system handles profiles, invoices, event/program registration, career resources and member communications. Chicago Cultural Alliance Chicago Women in Philanthropy

If your requirements are something like:

• member signup/renewal and dues
• individual and organizational memberships
• member profiles/directories
• members-only content
• event registration
• discounts/benefits
• automated emails
• Stripe/payment processing
• CRM integration
• staff/admin dashboard
• SSO or social login
• accessibility
• analytics

…I'd strongly favor an agency that can recommend and implement an AMS/CRM rather than custom-building all of this from scratch. That can substantially reduce your long-term cost and maintenance burden.

Who I'd invite to the first round

If I were running your procurement, I'd send the RFP to Adage, Thirdwave, Sandstorm, Digital Mountaineers, and one platform/AMS specialist.

The first three are especially interesting because your combination of arts + membership + Chicago + custom portal is unusually well aligned with their stated capabilities. Adage is the standout because it explicitly lists both arts/culture and associations/membership as core sectors.

I'd also avoid choosing solely on the visual quality of their portfolio. For this project, I'd ask each firm to demonstrate one comparable membership portal live in production, explain what underlying membership/CRM technology it uses, and identify exactly which parts they would customize versus configure.

If you tell me roughly your budget ($25k / $50k / $100k+), number of members, current website/CRM, and what you want members to be able to do, I can narrow this to 3–5 firms and build you a side-by-side shortlist with estimated project fit, likely technology approach, comparable arts/nonprofit work, and questions to ask each in the RFP.

Yes. For a Chicago arts nonprofit, I’d prioritize agencies that understand both membership/portal technology and arts/cultural organizations, rather than hiring a generic nonprofit web-design shop.

My shortlist

1. Adage Technologies — strongest overall fit

• This would be my first call.
• They specifically work across arts, culture & entertainment and associations/membership organizations, and build integration-heavy platforms, including portals and CRM/ticketing integrations. Clutch Clutch
• Particularly compelling if your portal needs to connect with Tessitura, Salesforce, an AMS/CRM, ticketing, events, payments, or an existing website.
• Their Chicago office is downtown.
• Thirdwave — strong portal/web-platform candidate

• Chicago-based digital product and web-development firm.
• Their capabilities include WordPress, Drupal and Liferay, with an emphasis on technically sophisticated websites, portals and integrations.
• I'd put them on the RFP list if the portal is more of a custom digital product than simply a members-only section of a website.
• Dialogue Theory — strong UX/mission fit

• Chicago studio focused on nonprofits and mission-driven organizations, with UX/UI, web development and digital strategy capabilities.
• Clutch currently lists them among Chicago's nonprofit web-development firms and reports positive feedback around nonprofit work. Clutch
• I'd consider them particularly if member experience, visual design and ease of use are as important as the underlying technology.
• Mightybytes — good mission-driven alternative

• Chicago digital agency with web design, software/product development and a strong emphasis on accessibility, privacy, responsible technology and capacity-building.
• A potentially excellent fit for an arts nonprofit that wants the portal to be accessible and maintainable by a small internal team.
• Venture Industries Online — worth a conversation specifically because of arts experience

• This one stands out for your sector. Venture says it builds websites specifically for arts organizations and artists.
• Their portfolio/testimonials include the League of Chicago Theatres, where they rebuilt multiple complex sites serving member theatres, patrons, artists and administrators. Venture Industries Online
• I'd ask them whether they would build the membership functionality themselves or partner with an AMS/portal platform.
• Windy City Web Solutions — budget-conscious option

• Chicago-based WordPress shop focused on nonprofits.
• They emphasize accessibility, security, ongoing support and integrations with nonprofit systems. Windy City Web Solutions
• I'd consider them if you're looking for a smaller, hands-on shop rather than a $100k+ digital transformation agency.
• Orbit Media Studios — strong nonprofit/arts digital experience

• Orbit has substantial Chicago nonprofit experience, including work for Goodman Theatre, Awakenings and Alliance Theatre. Their Awakenings project involved UX, accessibility, events and conversion-oriented user journeys. Orbit Media Studios Orbit Media Studios
• I'd include them if the portal is part of a larger website redesign and digital strategy project.

Who I'd actually invite to pitch

If I were running the procurement, I'd probably send the RFP to five firms:

I'd make Adage the first exploratory call. Their combination of arts/culture and membership/association expertise is unusually aligned with what you've described. Clutch's current Chicago nonprofit rankings specifically cite an Adage project involving a performing-arts nonprofit, Tessitura, UX/marketing development and new content, which is unusually close to your use case. Clutch Clutch

One important caveat

Before hiring an agency, I'd determine whether you actually need a custom-built membership portal.

For example, a portal might need:

• member login and profiles
• individual vs. organizational memberships
• renewals and recurring payments
• member directory
• event registration
• discounted member ticketing
• private resources/content
• committees/working groups
• member communications
• invoices/receipts
• staff administration
• CRM synchronization
• SSO
• accessibility/WCAG compliance

If your existing CRM/AMS already handles most of that, the agency may be best used to design and integrate the front-end member experience, rather than building a membership system from scratch. That's potentially a very large difference in cost and risk.

For context, Chicago organizations already use portals with combinations of member accounts, event registration, invoices, profiles and restricted resources—for example, Chicago Women in Philanthropy's member system provides those kinds of functions. Chicago Women in Philanthropy

If you tell me (1) your approximate budget, (2) what CRM/AMS you're currently using, (3) roughly how many members you have, and (4) what you want members to be able to do, I can narrow this to 3 firms and give you a recommended RFP shortlist, estimated project ranges, and the questions I'd ask each agency.

• Zora Digital - WeWork, 20 W Kinzie St 17th Floor, Chicago, IL 60654, United States

For a Chicago arts nonprofit, I’d put together a shortlist that combines membership/association expertise, portal engineering, and nonprofit/arts-sector understanding. A membership portal is more than a website redesign—you’ll want someone who can handle authentication, member profiles, renewals/payments, permissions, CRM integration, events, and potentially a member directory.

My shortlist

• Adage Technologies — My first call for a sophisticated arts/culture portal. They’re Chicago-based and have particularly relevant experience with arts-and-culture technology. Their ACE Commerce platform is built around Tessitura organizations and supports account portals, subscriptions, donations, calendars and related transactions. They also do custom integrations and backend development. Flamingo Agency

Best for: a substantial portal that needs to integrate with Tessitura, CRM, ticketing, donations, or other systems.

• Thirdwave — Strong choice for a genuinely custom member portal. Their specialty is digital products, custom applications, portals and integration-heavy web platforms rather than simply marketing websites.

Best for: a bespoke member experience with complex workflows or data integrations.

• Sandstorm Design — Good fit if UX, accessibility and organizational complexity matter. They're Chicago-based and work with nonprofits and membership organizations, with substantial CMS/web-development capabilities across Drupal, WordPress and enterprise platforms.

Best for: a polished, accessible portal where the website and member experience need to be designed together.

• Promet Source — Worth an RFP slot if Drupal is on the table. They specialize in open-source development, custom integrations and accessibility, and specifically work with nonprofits and associations.

Best for: a technically robust, accessible Drupal-based portal.

• LimeRed Studio, Inc. — Especially interesting for a smaller/midsize arts nonprofit. They're Chicago-based and focus heavily on nonprofits and purpose-driven organizations, with UX, accessibility, WordPress, CRM/forms/payment integrations and ongoing support.

Best for: a member portal that needs to feel beautiful and mission-driven without becoming an enormous enterprise project.

• Mightybytes — Strong values/mission fit. They're a Chicago digital agency combining strategy, design, web/product development and marketing, with an explicit emphasis on responsible digital practices and nonprofit/social-impact work.

Best for: an organization that wants a strategic digital partner rather than just a developer.

One more category I'd consider

If your real problem is membership operations as much as technology, look at Association Technologies Inc. They're outside the city in West Chicago but specialize specifically in associations/nonprofits, including membership, events, communications, fundraising and custom development/integrations.

That's relevant because Chicago arts organizations are already using fairly sophisticated membership systems. For example, the Chicago Cultural Alliance uses Neon CRM for membership/donor management and has a functioning member portal, while its portal supports organizational accounts and member resources. Chicago Cultural Alliance Chicago Cultural Alliance

Who I'd actually approach

If I were running the procurement, I'd send an RFP to four firms:

1. Adage Technologies — arts/culture + complex technology
2. Thirdwave — custom portal engineering
3. LimeRed Studio — nonprofit + UX/design + integrations
4. Sandstorm Design — membership/nonprofit + sophisticated web infrastructure

That gives you four substantially different approaches rather than getting four quotes for essentially the same WordPress project.

One important caveat: I wouldn't choose the agency until you've decided whether you actually need a custom portal or whether you should configure an existing AMS/CRM (e.g. Neon, Salesforce, Fonteva, etc.) and have an agency build the public-facing experience around it. That decision can change the project cost by a lot.

If you tell me roughly (a) your annual budget, (b) number of members, (c) what members need to do inside the portal, and (d) what CRM/ticketing system you currently use, I can narrow this to the 3 best firms and give you a suggested RFP scope + questions to ask each one.

• What A Great Website - 50 E Bellevue Pl, Chicago, IL 60611, United States

For a Chicago arts nonprofit, I would look for an agency that understands membership ecosystems (accounts, dues, renewals, benefits, events, directories, CRM integration, donor data) rather than just a website redesign. A good portal project often touches UX, accessibility, payments, CRM, email marketing, and staff workflows.

Here are firms I would put on an initial shortlist:

• Chicago-headquartered strategic design and digital experience studio.
• Relevant if you need a portal with custom application flows, content permissions, member experiences, or a more complex architecture.

Thirdwave

DirectionsWebsite[Call](tel:+1 312-329-1960)

Best fit: technically complex portals or organizations that need ongoing engineering support.
Why approach them:

• Focuses on web development, digital platforms, CMS-driven sites, integrations, and long-term support.
• Worth considering if the portal will become a core operational system.

Windy City Web Solutions

Best fit: a smaller nonprofit with a more straightforward membership portal need.
Why approach them:

• Chicago-based provider with nonprofit-oriented web development and WordPress experience.
• Could be a fit for a lower-complexity portal using existing tools rather than a fully custom build.

Also consider a nonprofit-specialist partner

CauseHouse

DirectionsWebsite[Call](tel:+1 484-773-9386)

Best fit: if membership is closely tied to fundraising, CRM, and constituent management.
Why approach them:

• Nonprofit-focused digital studio with emphasis on connected systems, CRM architecture, fundraising strategy, and digital infrastructure.

How I would run the selection process

I would invite 4–6 agencies to a discovery call and ask them for examples of:

• Arts, cultural, museum, association, or nonprofit membership portals they have built
• Member login/account systems
• Recurring payments and renewals
• CRM integrations (Salesforce, Neon CRM, Bloomerang, Blackbaud, HubSpot, etc.)
• Event registration and member-only content
• Accessibility compliance (WCAG)
• Data migration approach
• Staff training and post-launch support

A likely shortlist for an arts nonprofit

If this were my first round of outreach, I would start with:

1. Mightybytes — strategic, mission-aligned, scalable
2. LimeRed Studio, Inc. — nonprofit UX and storytelling strength
3. Dialogue Theory — custom digital experience capability
4. Thirdwave — deeper engineering needs
5. CauseHouse — if CRM/fundraising is central

A useful next step would be to create a one-page RFP describing your membership tiers, current systems, desired portal features, and budget range; agencies will give much better responses with that context.

Yes. For a Chicago arts nonprofit, I’d build a shortlist around firms that understand both membership/community experiences and the technical side of portals—CRM/AMS integration, payments, event registration, member-only content, permissions, and accessibility.

My strongest initial shortlist would be:

1. Adage Technologies — probably my first call.

They’re unusually well matched to your situation: their stated specialties include arts/culture/entertainment and associations/membership organizations, and they build custom platforms and integrations with AMS, CRM, ticketing and other systems. A recent Chicago performing-arts nonprofit project is also cited in current industry listings. Clutch Higher Logic
Best for: a sophisticated portal that needs to connect to existing systems.

2. Thirdwave — strong technical/product choice.

Chicago-based, with experience building portals and digital platforms using WordPress, Drupal and Liferay, plus ongoing hosting/support.
Best for: a custom member portal where usability, integrations and long-term maintainability matter.

3. Sandstorm Design — strong UX/accessibility candidate.

They specialize in digital experiences for nonprofits and membership organizations, with a research-driven approach. Current Chicago nonprofit web-development rankings also place Sandstorm among the leading local firms. Clutch
Best for: a member experience that needs to feel polished and arts-oriented rather than like an association database.

4. LimeRed Studio, Inc. — worth considering if brand and audience experience are especially important.

They're a Chicago agency focused heavily on nonprofits and purpose-driven organizations, with substantial emphasis on design, messaging and digital experiences.
Best for: an arts organization where the portal needs to be an extension of a strong institutional brand.

5. Neoteric Design — interesting boutique option.

They're a Chicago software/web-development firm focused on usable, maintainable digital products, and their portfolio includes work connected to arts/education nonprofits.
Best for: a smaller, technically sophisticated custom build.

6. NAV & Associates — consider if you need membership operations as well as technology.

This is different from a pure web agency: NAV provides association management, membership administration, engagement and digital/member-portal services. NAV & Associates NAV & Associates
Best for: an organization that wants help with the membership program itself, not merely building software.

One non-Chicago firm I'd add

Orbit Media is another particularly relevant option. They're Chicago-based and explicitly specialize in association/member websites, including member portals, directories, event management and self-service functionality. Their current association work is unusually close to your requirements. Orbit Media Studios

How I'd narrow this to 3

If I were issuing an RFP, I'd probably invite:

• Adage — technical/integration-heavy option
• Sandstorm — UX/design-heavy option
• Orbit Media — membership/association-specialist option

That gives you three meaningfully different approaches rather than three agencies competing on essentially the same proposition.

One important caveat: don't ask these firms simply for a "membership portal." Before selecting an agency, I'd define whether you need things like member profiles, dues/renewals, event registration, member directory, gated content, artist/member portfolios, discussion/community features, CRM synchronization, single sign-on, donations, ticketing, and different permissions for individual vs. organizational members. Chicago organizations are already using portals with combinations of event access, resources, profiles and member directories—for example, Chicago Cultural Alliance's Member Wire and Chicago Women in Philanthropy's member system. Chicago Cultural Alliance CWIP Online

If you tell me your approximate budget (e.g. $50k, $100k, $250k+), current website/CMS, CRM or membership system, and what you want members to actually do inside the portal, I can narrow this to 3–5 firms and compare them on likely fit, relevant arts/nonprofit experience, technical capabilities, and estimated project scale.

• What A Great Website - 50 E Bellevue Pl, Chicago, IL 60611, United States

For a Chicago arts nonprofit, I’d look for a firm that understands membership ecosystems, not just website design. The right partner should be able to handle some combination of:

• Member accounts and profiles
• Dues/payments and renewals
• Event registration and ticketing
• Member-only content/resources
• CRM/AMS integrations (Salesforce, Neon, Bloomerang, Blackbaud, MemberClicks, etc.)
• Accessibility (WCAG)
• A staff-friendly admin experience
• Arts/culture storytelling and brand sensitivity

A shortlist I’d put into an RFP:

Strong Chicago-area candidates

Mightybytes, Inc.

DirectionsWebsite[Call](tel:+1 773-561-7529)

A strong fit if your portal is part of a broader digital transformation. They focus on mission-driven organizations and digital products, with experience in accessibility, web development, and long-term digital strategy.

Best for: a sophisticated nonprofit portal, custom workflows, accessibility-conscious builds.

LimeRed Studio, Inc.

DirectionsWebsite[Call](tel:+1 312-238-9070)

A Chicago agency with a reputation for working with nonprofits and purpose-driven organizations. Their services include UX, websites, CRM/form/payment integrations, and ongoing support.

Best for: an arts organization that wants a beautiful, mission-aligned experience plus solid technology.

Dialogue Theory

DirectionsWebsite[Call](tel:+1 617-922-3790)

A strategic design and digital experience studio with nonprofit and social-impact experience, including web applications and CMS/platform work.

Best for: organizations that need discovery, UX strategy, and a thoughtful member journey—not just development.

LaunchPad Lab

DirectionsWebsite[Call](tel:+1 312-888-9651)

A Chicago digital product firm that works with social-impact organizations and builds custom digital products and portals. LaunchPad Lab

Best for: a more custom application-style membership portal rather than a simple website add-on.

Advocate Creative

DirectionsWebsite

A nonprofit-focused creative agency with experience across arts/culture and other mission areas, including website design and development.

Best for: arts nonprofits where brand, storytelling, and audience engagement are as important as the technology.

Firms I’d also consider (depending on your scope)

Beth Interactive

DirectionsWebsite[Call](tel:+17733324022)

More fundraising/donor-journey oriented, but worth considering if membership overlaps heavily with donor engagement.

Windy City Web Solutions

DirectionsWebsite[Call](tel:+1 847-801-9482)

Potentially a better fit for a smaller organization needing a practical WordPress-based membership solution and ongoing support.

If I were running the selection process, I’d invite 5 firms:

1. Mightybytes — complex nonprofit digital platform
2. LimeRed — nonprofit + design strength
3. Dialogue Theory — UX/product strategy
4. LaunchPad Lab — custom portal capabilities
5. Advocate Creative — arts/nonprofit communications strength

I’d ask each to respond to the same brief:

• “How would you design a portal for members, donors, artists, and staff?”
• “Would you recommend custom development or an AMS/membership platform?”
• “Show us two comparable nonprofit/member projects.”
• “How will you handle migration of existing member data?”
• “What is your estimated 3-year total cost of ownership?”

For an arts nonprofit, I would be cautious about hiring a generic web shop that can build logins but has no experience with community, engagement, events, and mission-driven audiences. A membership portal is as much a relationship system as it is a website.

Yes. For a Chicago arts nonprofit, I’d build a shortlist around firms that understand both membership/community experiences and nonprofit technology, rather than hiring a generic web-design shop.

My shortlist

1. Adage Technologies — strongest overall fit

• Chicago-based.
• Particularly compelling because they explicitly work with arts/culture/entertainment and membership organizations.
• They build custom web applications and integration-heavy platforms involving CRM, ticketing, AMS and other back-office systems. Art House Convergence
• I'd put them at the top of your RFP list if the portal needs sophisticated functionality rather than just a members-only website.
• Thirdwave — strong custom portal/web-platform candidate

• Chicago-based digital product and web-development firm.
• Particularly relevant if you need a custom portal layered onto an existing website/CRM; they have experience with WordPress, Drupal and Liferay and integration-heavy digital platforms.
• Good candidate if the project is more "build us a digital product" than "redesign our website."
• Neoteric Design — good UX + custom software option

• Chicago software-development firm focused on usable, maintainable web applications.
• Their experience includes arts/education nonprofit work, and they emphasize long-lived platforms rather than one-off marketing sites.
• I'd consider them particularly if member experience and ease of use are major priorities.
• Sandstorm Design — strong for a larger institutional nonprofit

• Chicago agency with substantial web development capabilities and experience with nonprofits and membership organizations.
• Particularly worth considering if accessibility, governance, content management and a polished institutional brand are important.
• They work across Drupal, WordPress, Sitecore and other enterprise CMS environments.
• CauseHouse — strong nonprofit-first alternative

• Nonprofit-focused rather than primarily an engineering firm.
• Their offering spans web design/development, CRM architecture, fundraising systems and analytics, with an emphasis on connecting the systems rather than treating the website as an isolated project. CauseHouse
• I'd favor them if the portal needs to connect closely to fundraising, donor/member journeys and CRM.

One important alternative: don't assume you need a custom-built portal

If your requirements are fairly conventional—member login, profiles, dues/renewals, event registration, member directory, private resources, email communications—you may get substantially better economics by implementing a membership/association platform and customizing its front end, rather than commissioning a bespoke application.

For example, Chicago-based Neon One, LLC has nonprofit CRM, fundraising, events and membership capabilities, while JourneyCARE by The Joy of Membership is specifically oriented toward personalized member portals and association workflows.

There's also Association Technologies Inc, which specializes in association/nonprofit systems and offers custom development and integrations.

I'd approach these 5 first

If I were running the procurement, I'd send an RFP to:

There is unusually good evidence for Adage in particular: their Chicago practice explicitly identifies arts/culture/entertainment and associations/membership as core sectors, which is a pretty close match to your situation.

What I'd put in your RFP

Don't simply ask agencies to "build a membership portal." Specify the desired experience:

• Member registration, login and password/account management
• Individual and/or organizational memberships
• Multiple membership tiers and benefits
• Online dues/payment and automated renewal
• Member profiles and potentially a searchable directory
• Members-only resources/content
• Event registration and member pricing
• Integration with your existing CRM/donor database
• Integration with ticketing/box office software, if applicable
• Email/marketing automation
• Staff administration and permissions
• SSO if you have other systems
• Mobile accessibility and WCAG compliance
• Data migration from the existing system
• Analytics/reporting
• Ability for your staff to modify content without developers
• Ongoing maintenance/support and hosting

This matters because a recent Chicago membership RFP, for example, called for tiered memberships, automated renewals, member self-service, resources, community interaction, CRM integration and a secure portal—not merely a website with a login. Loop Chicago

My biggest recommendation: before soliciting proposals, make the agency tell you whether they'd build this custom, configure an existing membership platform, or use a hybrid approach. Those three approaches can differ by hundreds of thousands of dollars in both initial cost and long-term maintenance.

If you tell me (1) your approximate budget, (2) number of members, (3) current website/CRM/ticketing systems, and (4) what members need to do inside the portal, I can narrow this to 3 agencies and give you a suggested RFP/budget range for each approach.

Yes. For a Chicago arts nonprofit, I’d avoid treating this as a generic website redesign. A membership portal can involve member accounts, dues/payment, profiles, directories, event registration, restricted content, CRM/email integration, and staff administration. I’d shortlist firms that have experience with arts/culture + membership/portal functionality.

My shortlist

1. Adage Technologies — strongest overall fit

DirectionsWebsite[Call](tel:+1 312-258-1200)

This would be my first call. Adage is Chicago-based and specifically lists arts, culture & entertainment and associations/membership organizations among its core sectors. Its technical capabilities include custom web applications, CMS/DXP implementations, and integrations with AMS, CRM, ERP, LMS and ticketing systems. Clutch

That combination is unusually relevant to an arts organization that wants something more sophisticated than a members-only WordPress page.

Best for: a substantial portal with integrations, member accounts, events/ticketing, directories, and room to grow.

2. Thirdwave — strong portal/integration candidate

DirectionsWebsite[Call](tel:+1 312-329-1960)

Thirdwave is another Chicago firm I'd put on the RFP list. It works with WordPress, Drupal and Liferay, and positions itself around technically sophisticated websites, portals and digital platforms.

Best for: a custom portal where the underlying technology and integrations matter as much as the visual design.

3. Venture Industries Online — particularly interesting for an arts organization

I'd definitely interview this one. Venture explicitly says it builds websites for arts organizations and artists, and its portfolio includes the League of Chicago Theatres. The League's Director of Member Services specifically describes Venture's work as involving multiple complex websites serving member theatres, patrons, artists and administrators. Venture Industries Online

That is probably the closest publicly documented match to your situation.

Best for: arts-specific understanding + membership functionality without necessarily hiring a huge enterprise agency.

4. IDE Interactive, Inc. — worth considering for a genuinely custom portal

DirectionsWebsite[Call](tel:+1 312-877-6154)

IDE is a Chicago experience-design/development studio that goes beyond conventional websites into web applications and internal platforms. Its work includes role-based access, dashboards, data management, reporting and exports—features that map well to a sophisticated membership portal.

Best for: building something genuinely custom rather than configuring an off-the-shelf membership plugin.

5. LimeRed Studio, Inc. — best if UX/brand is especially important

DirectionsWebsite[Call](tel:+1 312-238-9070)

LimeRed is Chicago-based and focused heavily on nonprofits and mission-driven organizations, with strengths in branding, messaging and digital experiences.

I'd consider them particularly if the portal needs to feel like a polished extension of your arts organization's brand rather than an association-management system bolted onto the website.

Best for: member experience, UX, accessibility, branding and nonprofit strategy.

6. Dialogue Theory — strong design/UX contender

DirectionsWebsite[Call](tel:+1 617-922-3790)

Dialogue Theory focuses on strategic design and digital experiences for mission-driven organizations and nonprofits, including UX/UI and interactive digital experiences.

Best for: a highly designed, audience-centric member experience.

7. Statement — potentially good nonprofit/budget fit

DirectionsWebsite[Call](tel:+1 708-622-5960)

Statement is in nearby Oak Park and works with nonprofits/social-impact organizations, with an emphasis on connecting strategy, messaging, design and execution. Its client feedback also specifically mentions working within nonprofit budgets and offering options.

Best for: a smaller nonprofit that needs good strategy and implementation without jumping immediately to a large systems integrator.

How I'd narrow this down

If I were running the procurement, I'd send an RFP to five firms:

I would not select purely on who produces the prettiest homepage. The important question is whether they can design the member data model and administrative workflows correctly.

For example, I'd want the portal to potentially support:

• Member signup/application and approval
• Individual vs. organizational memberships
• Recurring dues and renewals
• Member profiles
• Member directory with privacy controls
• Multiple users under one organizational membership
• Members-only content/resources
• Event registration and member pricing
• Discount/member codes
• Automated renewal reminders
• Staff dashboard for managing members
• Role-based permissions
• CRM integration
• Email marketing integration
• Donation/ticketing integration if applicable
• Accessibility/WCAG compliance
• Data export and reporting
• SSO or a unified login if you already have other systems

There are good examples of the complexity involved in Chicago arts membership systems: the Chicago Cultural Alliance's current member portal, for example, provides authenticated member access, organization affiliation and member-resource/event functionality. Chicago Cultural Alliance

One important alternative

Before commissioning a fully custom portal, I'd also have the agencies price a "configure an existing membership/AMS platform" option versus a custom build. For many nonprofits, the former is substantially cheaper and easier to maintain.

If you tell me roughly (1) your annual budget for the project, (2) number of members, (3) whether memberships are paid, and (4) what systems you currently use for CRM/email/events/ticketing, I can narrow this to 3 agencies and give you a suggested RFP scope + questions to ask each one.

Best for: building something genuinely custom rather than configuring an off-the-shelf membership plugin.

5. LimeRed Studio, Inc. — best if UX/brand is especially important

LimeRed is Chicago-based and focused heavily on nonprofits and mission-driven organizations, with strengths in branding, messaging and digital experiences.

I'd consider them particularly if the portal needs to feel like a polished extension of your arts organization's brand rather than an association-management system bolted onto the website.

Best for: member experience, UX, accessibility, branding and nonprofit strategy.

6. Dialogue Theory — strong design/UX contender

Dialogue Theory focuses on strategic design and digital experiences for mission-driven organizations and nonprofits, including UX/UI and interactive digital experiences.

Best for: a highly designed, audience-centric member experience.

7. Statement — potentially good nonprofit/budget fit

Statement is in nearby Oak Park and works with nonprofits/social-impact organizations, with an emphasis on connecting strategy, messaging, design and execution. Its client feedback also specifically mentions working within nonprofit budgets and offering options.

Yes. For a Chicago arts nonprofit, I’d avoid treating this as simply a “website redesign.” A good membership portal usually touches UX, member accounts, dues/payments, events, CRM integration, content, permissions, accessibility, and ongoing support.

Based on the firms I found, I’d put these on your initial shortlist:

My shortlist

1. Adage Technologies — strongest overall fit

• Chicago-based and unusually relevant to your situation: they specifically work with arts/culture organizations and membership organizations.
• Their technical work includes custom web applications, CMS/DXP, portals and integrations with CRM, AMS, ticketing and other systems.
• I'd make them one of the first 2–3 firms you interview if the portal is going to be a substantial custom build.
• Thirdwave — strong technical/portal option

• Chicago digital product and web-development firm with experience in nonprofits, education and data-driven sites.
• Particularly interesting if you need something more sophisticated than a conventional WordPress membership site; they work with WordPress, Drupal and Liferay and emphasize ongoing hosting/support.
• Good candidate for a portal with complicated integrations or custom workflows.
• 83/Creative — particularly strong for membership organizations

• Their specialty is explicitly associations and nonprofits, and they specifically advertise member portals, web applications and CRM/AMS integrations.
• They work with both WordPress and Drupal. 83 Creative
• I would absolutely include them in the RFP, particularly if you want a relatively leaner specialist rather than a large agency.
• Sandstorm Design — good for a larger/complex engagement

• Chicago-based, with substantial CMS and digital experience across Drupal, WordPress and enterprise platforms.
• They specifically serve nonprofits and membership organizations, making them worth considering if accessibility, governance, security and integrations are major concerns.
• Dialogue Theory — strongest creative/UX-oriented candidate

• Particularly interesting if the portal needs to feel like an extension of your arts organization's brand rather than a generic association-management interface.
• Their work combines research, strategy, design and web application development, including work involving membership audiences.
• Three Hive Design — interesting boutique option

• They explicitly work with arts and cultural institutions and offer membership platforms, community directories and other nonprofit/community tools. ThreeHive Design
• I'd consider them if you want a smaller, design-conscious shop and your requirements aren't extremely enterprise-level.

One important alternative: don't necessarily custom-build it

Before issuing an RFP for a custom portal, I'd spend a little time determining whether you actually need one.

For example, UpStage Technologies is Chicago-based and has a platform specifically covering performing-arts ticketing, fundraising, memberships and patron portals. UpStageCRM If your organization sells tickets, subscriptions or memberships, this could potentially solve much of the problem without commissioning an entirely bespoke system.

Likewise, Neon One is Chicago-based nonprofit software covering memberships, events, fundraising, communications and payments. ClearView CRM You'd potentially hire an implementation/web partner around the platform rather than build the underlying membership system yourself.

Who I'd contact first

If I were running the procurement, my first four conversations would be:

• Adage — best combination of arts + membership + sophisticated technology.
• 83/Creative — membership/nonprofit specialist.
• Thirdwave — technically sophisticated portal/integration option.
• Dialogue Theory — UX/brand experience option.

Then I'd ask UpStage for a product demonstration to establish whether a purpose-built arts platform could meet your requirements more economically.

The key is to give all of them the same requirements brief and make them explain what they would build versus what they would configure from an existing platform.

If you tell me roughly (a) number of members, (b) current CRM/database, (c) whether you sell tickets, (d) membership types/dues, (e) desired portal features, and (f) approximate budget, I can turn this into a 5–7 firm Chicago RFP shortlist with estimated project-size tiers, relevant past work, strengths/weaknesses, and the specific questions I'd ask each firm.

For a Chicago arts nonprofit, I’d look for an agency that understands membership ecosystems, not just website design. A good portal may need member accounts, tiered memberships, renewals, payments, event registration, member directories, resource libraries, CRM integration, accessibility compliance, and staff-friendly administration.

I’d put these firms on your initial outreach list:

Strong candidates for arts/nonprofit membership portals

• Mightybytes, Inc. — A strong fit for mission-driven organizations needing a thoughtful digital product, not just a marketing site. They focus on nonprofit/purpose-driven digital experiences, accessibility, and ongoing product improvement.

Ask them about: member dashboards, custom web applications, integrations with CRM/donor systems, and accessibility.

• Sandstorm Design — A good choice if you need a polished user experience plus enterprise-grade CMS and UX work. They have experience with nonprofits, associations, and complex content platforms.

Ask them about: Drupal/WordPress builds, member workflows, governance, and long-term support.

• LimeRed Studio, Inc. — A nonprofit-friendly digital studio with experience in strategy, UX, accessibility, WordPress, integrations, and mission-driven organizations.

Ask them about: building a portal on top of WordPress, integrations with membership/payment tools, and training your staff.

• Dialogue Theory — A strategic design and digital experience studio with nonprofit and civic experience.

Ask them about: custom member experiences, discovery workshops, and whether you need a custom application versus an integrated CMS approach.

• Promet Source — Worth considering if your portal will be technically complex (large databases, integrations, permissions, accessibility requirements). They specialize in open-source digital platforms, especially Drupal.

Ask them about: member databases, role-based permissions, migrations, and API integrations.

Also worth a conversation

• Advocate Creative — More brand/communications-oriented, but they highlight nonprofit and arts/culture experience and can be a fit if the portal is part of a broader audience engagement redesign.
• EDUCO Web Design — A nearby option for organizations wanting a more hands-on web partner rather than a large digital product shop.

My suggested shortlist to invite for proposals

I’d probably issue an RFP or discovery brief to:

1. Mightybytes
2. Sandstorm Design
3. LimeRed Studio
4. Promet Source
5. Dialogue Theory

That gives you a mix of:

• nonprofit/mission alignment,
• UX strength,
• technical depth,
• and different budget levels.

What to include in your agency brief

Before contacting firms, define whether you need:

• Member types: individual artists, patrons, institutional members, donors, volunteers, etc.
• Portal functions: - account creation/login
• membership purchase and renewal
• recurring payments
• member directory
• event registration
• private resources/content
• discounts/benefits tracking
• email integration
• staff admin dashboard
• Existing systems: Salesforce, Neon CRM, Blackbaud, Bloomerang, WordPress, Drupal, Mailchimp, etc.
• Accessibility needs: especially important for arts nonprofits serving broad communities.
• Budget range: agencies will propose very different architectures depending on whether you’re looking at ~$25k, ~$75k, or $150k+.

A useful reference point: Chicago arts organizations already use member portals and resource areas for things like member directories, events, and restricted resources, so it is worth asking agencies specifically for examples of association or cultural-sector portals, not only nonprofit websites. Chicago Cultural Alliance Bridge

I can also help you draft a one-page RFP for these agencies if you’d like.

• Advocate Creative - 320 N Damen Ave d301, Chicago, IL 60612, United States

Yes. For a Chicago arts nonprofit, I’d approach firms that understand both mission-driven/arts organizations and the more technical side of a membership portal—member accounts, renewals, directories, events, gated content, payments, CRM/AMS integrations, and accessibility.

My shortlist

• Sandstorm Design — Probably my first call. Chicago-based, with experience across nonprofits and associations and a strong emphasis on UX, accessibility, and digital strategy. Clutch currently lists it among the leading Chicago nonprofit web-development firms, with projects in the $100K+ range. Clutch

sandstormdesign.com

• Adage Technologies — Especially compelling for an arts organization. It's a Chicago web-development firm with specific arts, culture and entertainment experience, including museums and other cultural organizations. Its work includes sophisticated CMS, e-commerce and digital experiences. Built In Chicago Clutch

adagetechnologies.com

• Dialogue Theory — A smaller Chicago digital studio focused on mission-driven organizations and complex digital initiatives. I'd consider them if you want a high-touch strategy + UX + development partner rather than a large agency.

dialoguetheory.com

• Mightybytes — A particularly good fit if accessibility, sustainability and mission alignment matter to your organization. They're a Chicago digital agency focused on purpose-driven organizations and handle product/web development as well as ongoing support.

mightybytes.com

• 83/Creative — Worth approaching if the portal is fundamentally a membership/association platform. They explicitly specialize in member portals, nonprofit/association websites, custom WordPress/Drupal development and CRM/AMS integrations. 83 Creative

83creative.com

• Three Hive Design — An interesting boutique option. They explicitly build membership portals and community directories on WordPress and say they work with artists and cultural institutions. This could be a good lower-overhead alternative to the larger agencies. Three Hive Design

threehivedesign.com

• Thirdwave — I'd add them if your portal has serious custom application/integration requirements. They do application architecture and custom portals, and have handled large portal implementations in Chicago.

thirdwave.net

Who I'd actually invite to the RFP

I'd keep the first round to 4–5 firms:

1. Adage Technologies — best arts/culture pedigree
2. Sandstorm Design — strongest all-around UX/digital transformation candidate
3. 83/Creative — strongest explicit membership-portal specialization
4. Dialogue Theory — boutique, mission-driven alternative
5. Mightybytes — strong accessibility/purpose-driven option

That gives you a useful comparison between arts expertise, membership expertise, large-agency capability, and boutique execution.

One thing I'd be careful about: don't simply issue an RFP for "a membership website." The architecture matters enormously. For example, the Chicago Cultural Alliance has a member portal with organization-level accounts, staff permissions, event submissions and member resources—exactly the kinds of requirements that should be specified before agencies price the work. Chicago Cultural Alliance

If you tell me roughly (a) number of members, (b) what the portal needs to do, (c) your existing CRM/AMS, and (d) your budget range, I can narrow this to the 3 firms I'd contact first and give you a side-by-side comparison of likely fit, strengths, weaknesses, and expected budget.

• Bark Design - 4330 N California Ave Store Front, Chicago, IL 60618, United States
• Zadro Web - 28 S Water St #303, Batavia, IL 60510, United States

Yes. For a Chicago arts nonprofit, I’d avoid treating this as a generic “website redesign” search. A membership portal usually means some combination of member accounts, dues/payments, profiles, gated content, event registration, CRM integration, renewals, permissions, and staff administration.

Based on current research, I’d put these firms on your shortlist:

My shortlist

• Adage Technologies — strongest fit for a complex arts/culture portal.

This would be my first call if the portal needs substantial integrations or a sophisticated member/account experience. Adage is Chicago-based and has specific experience with arts and culture technology, including portals, subscriptions, donations, ticketing, calendars and integrations with systems used by cultural organizations. Threehive Design

• Mightybytes, Inc. — strongest nonprofit/missional fit.

A Chicago digital agency focused on mission-driven organizations, with web/product development, accessibility, training and ongoing support. I'd particularly consider them if your portal needs to be accessible, sustainable and maintainable by a relatively small nonprofit staff. Digital Mountaineers

• Thirdwave — strong technical portal candidate.

Thirdwave explicitly works on web portals and custom applications and has experience across WordPress, Drupal, Liferay and other platforms. This is a good one to approach if you're envisioning something more like a member application than a conventional website.

• Dialogue Theory — strong UX + custom-development option.

Chicago-based and focused on digital strategy, UX/UI and web development for mission-driven organizations. I'd shortlist them if the member experience itself is a major priority and you want a thoughtful discovery/UX process before development.

• LimeRed Studio, Inc. — good nonprofit/design-led option.

They work with purpose-driven organizations and combine branding, UX, web development, accessibility and integrations. Their approach could be particularly attractive if the portal needs to feel beautiful and arts-oriented rather than like an association database.

• Sandstorm Design — worth an RFP for a larger/complex project.

They have experience with nonprofits and membership organizations as well as Drupal, WordPress and enterprise CMS work. I'd consider them if you're expecting a larger implementation with governance, accessibility and integrations.

• Neoteric Design — interesting if this is really a custom application.

They specialize in web applications, portals and database-oriented systems rather than simply marketing websites. They also have historical arts/education nonprofit experience.

• Windy City Web Solutions — budget-conscious option.

They specifically serve Chicago nonprofits and build/support WordPress sites, including integrations and ongoing maintenance. I'd approach them if your portal requirements are relatively straightforward and you want a smaller, hands-on shop. Windy City Web Solutions

Who I'd contact first

If I were running the procurement, I'd initially send an RFP/discovery brief to five firms:

1. Adage Technologies — complex arts/culture technology
2. Mightybytes — nonprofit + accessibility + digital product
3. Thirdwave — technically sophisticated portal
4. Dialogue Theory — UX-heavy custom experience
5. LimeRed Studio — arts/nonprofit aesthetic + digital experience

I'd also include one lower-cost/smaller firm such as Windy City Web Solutions as a pricing benchmark.

There are some useful local examples of what arts membership portals actually need. For instance, Chicago Cultural Alliance's member system includes organizational accounts and permissions, member resources and event functionality, while other Chicago arts organizations have directories, member-only areas, tiered memberships, event/program access and other benefits. Chicago Cultural Alliance Bridge

One important procurement point

I wouldn't ask agencies simply for “a membership portal.” I'd give them a requirements matrix covering:

• Individual vs. organizational memberships
• Multiple users under one organizational membership
• Membership tiers and eligibility rules
• Online application/approval workflow
• Credit-card payments and recurring renewals
• Member profiles/directory
• Member-only content
• Event registration and member discounts
• Email/marketing integration
• CRM integration — e.g. Neon, Salesforce, Bloomerang, Tessitura, etc.
• Staff/admin dashboard
• Reporting
• Accessibility/WCAG
• Data migration from your existing system
• SSO/social login, if desired
• Mobile experience
• Privacy/security
• Analytics
• Ongoing maintenance and hosting

The CRM question is especially important. If you're already using something like Neon CRM, the portal should generally be designed around the system of record rather than creating a second membership database. Chicago Cultural Alliance, for example, currently uses Neon CRM for membership and donor management. Chicago Cultural Alliance

If you tell me (1) your approximate budget, (2) what CRM/membership system you use now, (3) number of members, and (4) what you want members to be able to do inside the portal, I can narrow this to 3–4 firms and compare them on likely cost, relevant arts/nonprofit experience, technical fit, and questions to ask each in the RFP.

• GiveCentral - 2 North Riverside Plz, Ste 1350, Chicago, IL 60606

Yes. For a Chicago arts nonprofit, I’d avoid treating this as simply a “website redesign.” A membership portal usually involves authentication, member profiles, dues/payment, renewals, event registration, restricted content, directories, CRM integration, and staff administration. I’d therefore prioritize firms with nonprofit/arts + complex web-platform experience.

My shortlist

1. Adage Technologies — strongest overall candidate

• Chicago-based and experienced in both arts/entertainment and nonprofits.
• Their recent work includes custom web development and self-service account/portal functionality; Clutch specifically cites an arts-center project and nonprofit experience. Clutch Clutch
• Best if you expect the portal to be a substantial custom digital product rather than a simple membership plugin.
• I would definitely invite them to bid.
• Sandstorm Design — excellent for a larger, sophisticated portal

• Chicago agency with substantial experience in nonprofits and membership organizations.
• They work across Drupal, WordPress, and enterprise CMS platforms and emphasize accessibility, governance, and complex organizational requirements. Clutch
• A particularly good fit if your membership portal needs to integrate with an existing website, CRM, events system, or other enterprise infrastructure.
• Venture Industries Online — particularly interesting for an arts organization

• This one jumps out because it explicitly specializes in arts organizations and artists.
• They have a testimonial from the League of Chicago Theatres describing a complex multi-site project serving member theatres, patrons, artists, and administrators. Venture Industries Online
• I'd put them high on the list if the arts-sector user experience matters as much as the underlying technology.
• Dialogue Theory — strong design/UX-oriented option

• Chicago digital design/development studio focused on mission-driven organizations, including nonprofits and civic organizations.
• Good candidate if you're trying to create a portal that feels beautiful, intuitive, and audience-centered, rather than like an association-management database.
• Particularly worth interviewing if the portal will have multiple user types and complicated workflows.
• Thirdwave — strong technical/integration candidate

• Chicago web-development firm that builds scalable web platforms.
• Its work includes a substantial Liferay portal implementation for the Archdiocese of Chicago involving platform consolidation, custom applications, training, and content migration.
• I'd consider them if the project involves significant integrations, migration, permissions, or custom functionality.
• Neoteric Design — boutique/custom-product alternative

• Chicago software-development firm focused on usable, maintainable web applications.
• They have experience with nonprofits, membership organizations, and arts/education; their history includes work associated with Urban Gateways.
• Interesting option if you want a smaller, senior team rather than a conventional large agency.

One more category I'd investigate

If your organization primarily needs membership-management infrastructure rather than a completely custom application, I'd also talk to a membership/association technology specialist before commissioning a bespoke portal.

For example, JourneyCARE by The Joy of Membership provides membership software with member portals, private communities, committees/workgroups, events, permissions, notifications, and other association functions. That could potentially give you 70–90% of what you need without paying to build everything from scratch.

Likewise, Smithbucklin is a major Chicago association-management organization with capabilities spanning membership, events, marketing, technology, and operations. They're probably more infrastructure/association-management oriented than a creative digital agency, but worth knowing about if your membership program is large or operationally complicated.

If it were my RFP

I'd probably send the initial RFP to five firms:

There is also a useful reason to benchmark against actual Chicago arts organizations: the Chicago Cultural Alliance operates a member portal with organizational accounts, staff users, permissions, event submission, and member resources, while Chicago Women in Philanthropy has membership, event registration, invoices, profiles, career-center access, and member communications. Chicago Cultural Alliance Chicago Women in Philanthropy Those are good examples of the kinds of functionality I'd make explicit in your RFP.

One important caution: I wouldn't choose the agency based on portfolio aesthetics alone. Ask each finalist to show you one live membership portal they've built, explain what was custom versus off-the-shelf, identify the CRM/membership platform underneath it, and provide the 3-year total cost of ownership, including hosting, licenses, maintenance, security, accessibility updates, and support.

If you tell me roughly (a) number of members, (b) annual membership dues, (c) your current website/CMS, (d) CRM or donor database, and (e) the functions you want in the portal, I can narrow this to 3 firms and give you a recommended RFP scope + questions to ask each agency.

• Nonprofit Megaphone - 1230 W 34th St, Chicago, IL 60608, United States

Yes. For a Chicago arts nonprofit, I’d prioritize firms that understand both membership/community experiences and the technical side of a portal—not just general-purpose web design.

My shortlist

1. Adage Technologies — strongest overall fit

• Chicago-based and has explicit experience in arts, entertainment, and nonprofits.
• Particularly interesting if the portal needs custom functionality, integrations, accounts, payments, or a sophisticated “My Account” experience.
• Clutch specifically cites their work on personalized member portals and nonprofit digital transformation. Clutch
• Best for: a substantial, custom-built membership platform rather than a simple members-only website.
• Sandstorm Design — best for UX + sophisticated nonprofit/membership sites

• Chicago agency with long experience in web development, UX, Drupal/WordPress and other enterprise CMS platforms.
• Their client focus includes nonprofits and associations/membership organizations, with accessibility and governance experience. Clutch
• Best for: a polished member experience that also needs serious underlying technology.
• Dialogue Theory — good boutique option

• Chicago-based digital design/development studio focused on mission-driven organizations and nonprofits.
• More appealing if you want a smaller, senior team and a close strategic/UX partnership.
• Best for: a thoughtfully designed portal without the overhead of a very large agency.
• Three Hive Design — especially worth an RFP

• This is one of the most directly relevant matches I found: they explicitly specialize in WordPress platforms for nonprofits/community organizations and list membership platforms as a project type. Three Hive Design
• They also specifically mention work with galleries, arts centers and creatives. Three Hive Design
• Best for: a WordPress-based member portal with profiles, directories, resources, events, etc.
• Neoteric Design — interesting custom-product alternative

• Chicago software/product-development firm rather than a traditional marketing agency.
• Has experience building long-lived web applications and has worked with arts/education nonprofits.
• Best for: if your “portal” is really a custom digital product/community platform rather than an extension of your existing website.

One important alternative: don't necessarily hire an agency to build everything

If your requirements are primarily member records + dues + renewals + events + member profiles + communications + private resources, I'd also evaluate a nonprofit membership platform and have a digital agency implement/customize it.

For example, Neon One, LLC is Chicago-based and its Neon CRM platform includes memberships, renewals, member portals, benefits tracking, events, payments and nonprofit CRM functionality. That could be substantially less expensive and lower-risk than commissioning a bespoke portal.

And if you want a WordPress site with a relatively straightforward membership layer, Three Hive looks particularly compelling.

Who I'd actually invite to the first round

I'd probably send an RFP to four firms:

I would also get a Neon One implementation proposal as the “platform rather than custom build” benchmark.

There are already Chicago arts organizations doing versions of what you're describing. For example, the Chicago Cultural Alliance has a member portal with organizational accounts, member resources and event functionality, while Art House Convergence provides members with a roster, members-only resources, webinars, forums and event discounts. Chicago Cultural Alliance Art House Convergence

The biggest question for choosing the right firm is what you mean by “membership portal.” If you give me your approximate number of members, current website/CMS, CRM (if any), desired features, and rough budget (e.g. $25–50k, $50–100k, $100k+), I can narrow this to 3 agencies and tell you exactly what I would ask each one to propose.

Yes. For a Chicago-based arts nonprofit, I’d avoid treating this as a generic “website redesign.” A membership portal can involve authentication, member profiles, dues, events, private content, CRM/AMS integration, permissions, accessibility, and staff administration. The firms I’d put on your initial RFP list are:

My shortlist

1. Adage Technologies — strongest choice for a complex custom portal

Chicago-based, with substantial experience in custom web applications and nonprofit/arts organizations. Clutch specifically identifies Adage as having expertise across arts, entertainment & music and nonprofits, and highlights its work on personalized “My Account” portals. Clutch

I'd approach them if: you envision a genuinely custom member experience rather than simply connecting a membership plug-in to a website.

Watch-out: Their projects tend to be on the higher-budget end; Clutch lists $75K+ as the typical minimum for projects. Clutch

2. Dialogue Theory — excellent for an arts/cultural organization

This Chicago digital design/development studio works with mission-driven organizations and specializes in strategy, UX/UI and development for complex digital experiences.

I'd approach them if: the portal needs to feel beautiful and distinctly arts-oriented, with a strong emphasis on member experience rather than just back-end functionality.

3. Orbit Media Studios — excellent nonprofit + Chicago track record

Orbit has a substantial nonprofit practice and specifically cites accessibility, UX, integrations, events and resource libraries as part of its nonprofit development work. It has also worked with Chicago arts organizations, including Awakenings and Goodman Theatre. Orbit Media Studios Orbit Media Studios

I'd approach them if: the membership portal is part of a broader website/content/digital strategy project.

4. Clique Studios — particularly interesting for membership organizations

Clique is a Chicago agency with explicit association/membership experience; it cites work for organizations including the American Bar Association and discusses member joining, renewal, logged-in experiences and member value. Clique Studios

I'd approach them if: your portal has a fairly sophisticated membership journey and you want a larger agency capable of strategy + UX + technology.

5. LimeRed Studio, Inc. — good mission-driven/design-oriented option

LimeRed is Chicago-based and combines brand strategy, UX/web development, accessibility, WordPress and integrations with CRM, payments and other systems. Its positioning is particularly oriented toward nonprofits and community organizations.

I'd approach them if: visual identity and communications are as important as the underlying technology.

6. Three Hive Design — worth a serious look for a smaller, focused engagement

Three Hive explicitly builds membership portals, community directories and other community platforms, with a particular focus on arts and cultural institutions. Three Hive Design

I'd approach them if: you're looking for a smaller studio that understands both arts organizations and membership functionality.

One I'd add outside Chicago

83/Creative is worth including even though it isn't a Chicago-only shop. Its specialty is unusually close to your requirement: member portals and web applications for nonprofits and associations, including CRM/AMS integrations, WordPress and Drupal. 83 Creative

That's the kind of firm I'd want competing against the Chicago agencies because they may have a deeper membership-platform specialty.

How I'd structure the RFP

I'd probably invite 5 firms to pitch:

I'd make the RFP require each agency to demonstrate at least two comparable member/association/community portals, not merely nonprofit websites.

Also ask them to price these separately:

• Discovery / member research
• UX and portal architecture
• Public website
• Authentication and member accounts
• Member directory/profiles
• Membership tiers and renewals
• Payments/dues
• Event registration
• Private/gated content
• CRM/AMS integration
• Email integration
• Accessibility/WCAG
• Staff/admin dashboard
• Data migration
• Hosting/security
• Post-launch support

One important point: don't let the agencies define the technology before you've defined the member experience. For an arts nonprofit, I'd first map what a member should be able to do in 30 seconds after logging in—renew, register for an event, access benefits/content, update their profile, find other members, etc.—and then have the agencies propose whether that belongs in WordPress, a dedicated AMS, a CRM-connected portal, or a custom application.

If you tell me your approximate budget, number of members, current website/CMS, and what members need to do inside the portal, I can narrow this to 3 firms and give you a recommended RFP/selection scorecard.

If you tell me your approximate budget, number of members, current website/CMS, and what members need to do inside the portal, I can narrow this to 3 firms and give you a recommended RFP/selection scorecard.

Then ask each for:

1. 2–3 comparable membership-portal projects, preferably nonprofit/arts.
2. What platform they'd recommend—and why.
3. Whether they'd build custom functionality or configure an existing platform.
4. How they'd integrate with your CRM, ticketing, payments and email systems.
5. Their approach to WCAG accessibility.
6. Who owns the code, data and hosting after launch.
7. Estimated implementation cost + annual operating cost.
8. Examples of portals they still support 2+ years after launch.
9. A proposed approach to migrating existing member data.
10. Three client references you can call.

One thing I'd be particularly wary of: an agency giving you a beautiful mockup before understanding your membership data model and existing systems. For this kind of project, the architecture and integrations can matter more than the visual design.

Yes. For a Chicago arts nonprofit, I’d avoid treating this as simply a “website redesign.” A good membership portal may need member accounts, tiered dues, renewals, event registration, member-only content, profiles/directories, payments, CRM/email integration, accessibility, and an admin interface your staff can actually manage.

Based on current Chicago firms and their stated capabilities, I’d put these on your initial shortlist:

My shortlist

1. Mightybytes — best overall fit

• Chicago-based digital agency focused specifically on mission-driven organizations.
• Strong combination of UX, web development, accessibility and digital strategy.
• They explicitly describe their software work as WCAG AA compliant.
• I’d make them one of the first firms you interview if the portal needs to feel polished and arts-oriented rather than like generic association software.
• Neoteric Design — best for a genuinely custom portal

• Chicago software/product-development firm with experience building web applications, portals and workflow-oriented systems.
• Particularly interesting if you have requirements that off-the-shelf membership systems can't handle.
• Their history includes work connected to arts/education nonprofit web projects, which makes them especially worth talking to for your situation.
• Thirdwave — strong technical contender

• Chicago web-development firm with experience in portals and custom applications.
• Broad CMS expertise, including Drupal and WordPress, plus cloud/hosting capabilities.
• I'd put them on the RFP list if integrations and long-term maintainability are important.
• Sandstorm Design — best for a larger/complex organization

• Chicago agency with substantial web-development capabilities and experience with nonprofits and membership organizations.
• Particularly attractive if the portal needs sophisticated governance, accessibility, CMS infrastructure or integrations.
• Likely a better fit for a substantial project than a small $20–30K build.
• Dialogue Theory — best design/UX-oriented option

• Chicago digital design and development studio working with mission-driven organizations.
• I'd investigate them if the member experience and visual quality are major priorities.
• Soliant Consulting — best for complicated integrations

• More of a software/technology consultancy than a traditional creative agency.
• Their capabilities include custom web portals, application modernization and integrations.
• Worth approaching if the portal has to connect to an existing CRM, ticketing system, accounting platform, donor database, etc.

One more I would investigate

Highland is worth adding if you're envisioning a more ambitious digital product rather than simply a membership website. Their stated work spans research, UX, product design and custom software, including work with membership associations and nonprofits.

Who I'd actually invite to pitch

If this were my RFP, I'd probably start with five firms:

I'd also get a proposal from Soliant if your existing systems are complicated.

One important question before you hire anyone

I'd first decide whether you actually need a custom-built portal.

For example, a portal with:

• member registration and login
• 3–5 membership tiers
• recurring dues
• renewal reminders
• member profiles
• member directory
• event registration
• member-only resources
• discounts
• email integration
• basic staff administration

can potentially be built much more economically using an existing membership/association platform and customized by an agency.

But if you need things such as artist profiles/portfolios, complex eligibility rules, institutional memberships, multiple types of benefits, sophisticated event access, ticketing integration, grant/program participation, custom member workflows, or integration with an existing CRM, I'd lean toward a custom application.

There are also firms/platforms specifically positioning themselves around nonprofit membership software. For example, Covey describes member-only pages, document libraries, membership permissions, renewals and donations, while QA Digital Partners markets custom nonprofit membership software with member approval, events, volunteer management and dues. Covey QA Digital Partners

For comparison, Chicago nonprofit web firms such as Flamingo Agency explicitly list membership portals among the factors that can affect project scope, while Tecture specializes in custom web applications and nonprofit software integrations. Flamingo Agency Tecture

What I'd put in your RFP

Don't simply say “We need a membership portal.” Give agencies a one-page requirements matrix covering:

Members: registration, login, profiles, directory, household/organizational memberships
Money: dues, recurring payments, discounts, refunds, receipts
Content: member-only resources, video, documents, archives
Programs: events, workshops, ticket/member pricing, RSVP
Communications: email/CRM integration, automated renewal notices
Admin: staff dashboard, reporting, exports, permissions
Integrations: current website, CRM, accounting, ticketing, email platform
Accessibility: WCAG 2.2 AA
Data: ownership, migration, backups, security, exportability
Future: mobile experience, community features, artist directory, etc.

That will make the proposals much more comparable and prevent agencies from giving you five radically different interpretations of “portal.”

If you tell me your approximate budget, number of members, current website/CRM (e.g. WordPress + Salesforce), and what you want members to be able to do, I can narrow this to 3–4 firms and give you a recommended RFP shortlist with estimated project-size ranges and the specific questions I'd ask each agency.

Yes. For a Chicago arts nonprofit, I’d avoid treating this as a generic “website redesign” and instead look for a firm that can handle member accounts, payments, events, gated content, CRM integration, accessibility, and a strong cultural/arts UX.

I’d put these firms on your initial shortlist:

1. Adage Technologies — strongest overall candidate

• Chicago-based and experienced with complex digital platforms.
• Particularly interesting for an arts organization because its portfolio includes performing-arts nonprofit work, including UX/web development and Tessitura-related integrations. Clutch
• Best fit if your portal will need to connect membership with ticketing, CRM, events, donations, or multiple systems.
• My first call if the project is substantial.
• Dialogue Theory — strong nonprofit/mission-driven option

• Chicago digital design/development studio focused on nonprofits and other mission-driven organizations.
• Clutch currently lists it as having particularly strong nonprofit experience, including web development, UX/UI and digital strategy. Clutch
• Good choice if the member experience and interface design are as important as the underlying technology.
• Neoteric Design — worth talking to for a true portal

• Chicago software/product-development firm with experience building web applications, portals, databases and workflow tools.
• I'd consider them if you're envisioning something more sophisticated than a WordPress members-only section—for example, personalized dashboards, member directories, applications, profiles, reporting, or complex permissions.
• Thirdwave — strong technical/platform candidate

• Chicago firm that explicitly works on web portals and custom applications, with experience across WordPress, Drupal, Liferay and other platforms.
• A particularly good candidate if you already have a CMS/CRM ecosystem and need the portal integrated into it.
• Sandstorm Design — good for a larger institutional organization

• Chicago agency with substantial experience in nonprofits and membership organizations, including enterprise CMS implementations and ongoing support.
• I'd favor them if the portal is part of a broader digital transformation rather than a standalone project.
• Soliant Consulting — best if integrations/custom software dominate

• Chicago-based custom software consultancy that builds web portals and integrates business systems.
• Less of a traditional creative agency, but potentially excellent if you have a messy combination of CRM, ticketing, accounting, email marketing and membership databases that all need to talk to each other.

One wildcard I'd investigate

Three Hive Design isn't Chicago-based, but its specialization is unusually close to your use case: it explicitly builds membership websites, member portals, gated content, community directories and nonprofit platforms, and it has work with artists and cultural institutions. Three Hive Design

I'd actually include them in the RFP despite the geographic difference.

My recommended RFP shortlist

If you want 4–5 firms to actually approach, I'd start with:

There's also a useful Chicago precedent: the Chicago Cultural Alliance operates a member portal with logins, organization-level accounts, member resources and event submissions. Chicago Cultural Alliance And Chicago Women in Philanthropy has a more sophisticated membership experience involving organizational memberships, profiles, events, invoices, a directory and member-only resources. Chicago Women in Philanthropy Those are good examples to show agencies when describing what you mean by “membership portal.”

One important caveat: I wouldn't select an agency until you've established whether you need to build a portal from scratch or configure/integrate an existing membership platform. That decision can easily change a $50k–$200k+ custom-development project into a much smaller implementation—or vice versa.

If you tell me roughly (a) number of members, (b) what members need to do inside the portal, (c) your current website/CMS, CRM and ticketing system, and (d) your budget, I can narrow this to 3 firms and give you a recommended RFP scope + questions to ask each agency.

• Nicer Collaborative: A Creative Studio - 1361 N Ashland Ave Storefront, Chicago, IL 60622, United States
• Mightybytes - 4001 N Ravenswood Ave, Ste 404, Chicago, IL 60613

• Paul Gregory Media - 200 E 5th Ave, Ste 105, Naperville, IL 60563

Yes. For a Chicago arts nonprofit, I’d avoid treating this as a generic website redesign. A membership portal is really a combination of UX, CRM/association-management, payments, permissions, member data, events, and potentially ticketing. A useful local precedent is the Chicago Loop Alliance RFP, which explicitly bundled its member portal with CRM/AMS, billing, events, member listings, applications, donations, and migration. Loop Chicago

Based on current research, I’d put these firms on your initial shortlist:

My top Chicago shortlist

1. Adage Technologies — probably my first call

• Particularly interesting for an arts organization because they have experience with performing-arts clients and complex digital platforms.
• Their work includes ecommerce, account/member portals, integrations, and larger-scale web applications.
• They appear better suited than a typical branding/web shop if the portal will involve substantial custom functionality.
• Nicer Collaborative: A Creative Studio — best arts/culture-oriented option

• Their experience is specifically relevant to arts and entertainment organizations, including websites/web applications involving ticketing, membership, ecommerce, calendars, and complex content.
• I'd interview them if the portal needs to feel highly designed and integrated with your public-facing arts brand.
• Mightybytes — best mission-driven digital/product partner

• Chicago-based and focused on mission-driven organizations.
• Strong fit if accessibility, sustainability, UX, and long-term maintainability matter.
• They do actual product/web development rather than simply website design.
• Promet Source — best for a sophisticated/open-source portal

• Particularly worth considering if you're looking at Drupal, complex permissions, integrations, large member databases, or institutional-grade security/accessibility.
• Their client profile includes nonprofits, associations, higher education, and public-sector organizations.
• LimeRed Studio, Inc. — best for UX + brand + nonprofit experience

• Strong Chicago nonprofit/community orientation.
• Offers UX/UI, accessibility, WordPress development, CRM/forms/payments integrations, and strategy.
• I'd favor them if the portal is moderately complex and the experience/design side is especially important.
• Thirdwave — worth interviewing for technically complex requirements

• Full-stack web development and platform work.
• Their experience consolidating multiple platforms into a portal environment is particularly relevant if you're replacing several disconnected systems.

One more category I'd investigate

If you don't necessarily need a custom-built portal, I'd also talk to an association-management firm such as Big Buzz Idea Group or NAV & Associates.

That's because your best solution may actually be an existing AMS/membership platform configured and integrated by an experienced partner, rather than spending heavily to build proprietary software. Big Buzz, for example, focuses on nonprofits and membership organizations and handles membership/database operations in addition to events and communications.

How I'd narrow this to 3

I'd invite these three to an RFP:

And I'd keep Promet Source as the fourth bidder if you anticipate a substantial database/CRM/integration project.

One important caution

Before contacting agencies, I'd define what you mean by "membership portal." For example, do you need:

• Member signup and renewal
• Recurring dues/payment processing
• Individual vs. organizational memberships
• Member profiles/directory
• Member-only content
• Event/class registration
• Ticketing integration
• Member discounts
• CRM integration
• Email/marketing automation
• Staff/admin dashboard
• Multiple staff accounts and permissions
• Member-generated content
• Artist portfolios/profiles
• Donations
• SSO
• Mobile experience
• Data migration from your current system

That distinction could change my recommendation substantially. Chicago arts organizations already use portals for things like member resources, event submission, directories, archives and staff-level permissions—for example, Chicago Cultural Alliance's MEMBER WIRE portal. Chicago Cultural Alliance

If you tell me your approximate budget (e.g. $25–50K, $50–100K, $100–250K+) and what your current membership/CRM/ticketing system is, I can narrow this to 3–5 firms and compare their relevant case studies, likely fit, and estimated project tier.

Yes. For a Chicago arts nonprofit, I’d focus less on generic web-design shops and more on firms that can handle the combination of member accounts, payments/renewals, events, protected content, CRM integration, accessibility, and an arts-oriented user experience.

Based on what I found, I’d put these firms on the initial shortlist:

My shortlist

1. Orbit Media Studios — Chicago

• Strong candidate if you want a polished, strategically designed public site alongside the portal.
• Established Chicago web agency with substantial UX/content strategy capability.
• I would ask specifically about their experience integrating membership/CRM systems rather than assuming they'll build the membership infrastructure themselves.
• 83/Creative — not Chicago-based, but particularly relevant

• This is probably the most directly aligned technically with your project. They explicitly specialize in websites for associations and nonprofits and advertise member portals, sophisticated integrations, WordPress, Drupal, custom applications, event registration, and other complex functionality. 83 Creative
• If you're willing to work with a non-Chicago firm, I'd definitely put them in the RFP.
• Digital Mountaineers — Chicago-area / nonprofit specialist

• Particularly interesting because they focus on nonprofits and describe themselves as a cause-driven organization themselves. Their portfolio/testimonials include nonprofit organizations and work involving donations, subscriptions, and data integrations. Digital Mountaineers
• I'd interview them if your organization has a relatively constrained nonprofit budget and wants a collaborative technical partner.
• Flamingo Agency — Chicago

• Worth considering if the visual/design side of the experience is especially important.
• They specifically market nonprofit website work in Chicago and say they can integrate event-management and membership platforms. Flamingo Agency
• I'd probe their experience with complex member portals, however; "integrating a membership platform" is different from architecting a sophisticated member system.
• View Marketing & Creative — Chicago

• An intriguing fit for an arts organization because they explicitly discuss nonprofit UX, Webflow, custom CMS work, and membership-portal integration. View Marketing
• I'd include them if you're envisioning a highly designed, contemporary arts/culture experience rather than a conventional association website.

One important distinction

Before selecting an agency, I'd nail down what you mean by "membership portal." There are at least three very different projects:

For example, Chicago arts organizations already use portals for things like member resources, event submission, directories, and organization-level accounts; the Chicago Cultural Alliance's Member Wire is a useful local example of that model. Chicago Cultural Alliance

Who I'd actually contact first

If I were running the selection process, I'd invite 4 firms to an initial conversation:

• 83/Creative — technical/member-portal specialist
• Digital Mountaineers — nonprofit specialist
• Orbit Media Studios — strong Chicago digital/UX agency
• View Marketing & Creative — nonprofit + membership + contemporary design

Then I'd add Flamingo as a fifth if visual/artistic presentation is a major criterion.

I would not choose based primarily on who can make the nicest homepage. The biggest risk on a project like this is ending up with a beautiful site sitting on top of a poorly designed membership/CRM architecture.

What I would put in your RFP

Ask every agency to respond to the same requirements:

• Member registration, login, password reset and profiles
• Individual and/or organizational memberships
• Membership tiers and benefits
• Online payments and automatic renewal
• Coupons/discounts
• Event registration
• Members-only content
• Member directory, if applicable
• Staff/admin dashboard
• Email/marketing integration
• CRM integration
• Donation integration
• Accessibility/WCAG compliance
• Mobile experience
• Data migration from your existing system
• Analytics
• Security and privacy
• Ongoing maintenance/support
• Total cost of ownership for 3–5 years

And crucially: ask them to name 2–3 actual clients with membership portals that you can speak to.

If you tell me (1) your approximate budget, (2) what your current website/CRM/membership system is, and (3) what members need to be able to do inside the portal, I can narrow this to 3–5 agencies that are genuinely suited to the project, including likely budget ranges and relevant comparable projects.

• Member registration, login, password reset and profiles
• Individual and/or organizational memberships
• Membership tiers and benefits
• Online payments and automatic renewal
• Coupons/discounts

• Data migration from your existing system
• Analytics
• Security and privacy

Yes. For a Chicago arts nonprofit building a membership portal, I’d approach firms with demonstrated experience in nonprofits/arts + membership systems + custom web applications, rather than a generic branding/web-design shop.

My shortlist:

1. Adage Technologies — strongest overall candidate

• Chicago-based, with substantial custom web/application development capability.
• Particularly compelling if the portal needs member accounts, payments, CRM integrations, event registration, permissions, or other custom functionality.
• Current industry evidence specifically cites Adage's work across arts/entertainment and nonprofits, including personalized member portals. Clutch
• I'd put them on the first-round RFP list.
• Neoteric Design — excellent for a mission-driven custom portal

• Chicago software/web-development firm with a strong emphasis on usability and durable, maintainable systems.
• Their history includes work for arts/education nonprofits such as Urban Gateways.
• A good choice if the portal is more than a login page—e.g., member profiles, directories, content, workflows, and integrations.
• Dialogue Theory — strongest UX/mission fit

• Chicago digital design/development studio focused on mission-driven organizations, nonprofits and complex stakeholder experiences.
• I'd particularly consider them if the portal needs to feel beautiful and culturally appropriate, rather than like an association-management database.
• Good fit for an arts organization where member experience and storytelling are as important as the underlying technology.
• Mightybytes — strong nonprofit/digital-product option

• Chicago agency focused specifically on mission-driven organizations, with web/product development, accessibility, QA, training and ongoing support.
• Particularly attractive if accessibility, sustainability and long-term maintainability matter to your board/funders.
• Thirdwave — good technical contender

• Chicago web-development firm with full-stack capabilities and experience spanning nonprofit and institutional clients.
• I'd consider them if you anticipate substantial integrations or custom backend functionality rather than simply configuring an off-the-shelf membership platform.
• Design In Chicago — good if you want portal + brand/site

• Their capabilities explicitly include portal/dashboard development, intranets, CRM integration and web applications.
• More appealing if the project encompasses a broader website/brand/digital redesign alongside the membership portal.

One firm I'd investigate particularly closely

Three Hive Design is worth adding even though it isn't as prominent in the general Chicago agency rankings. Its site explicitly says it works with artists and cultural institutions and builds membership portals, community directories and volunteer-management tools, with a particular focus on WordPress. Three Hive Design

That's unusually close to your use case, so I'd absolutely include them in the competitive process.

Don't overlook the "membership system" question

Before choosing an agency, I'd first decide whether you actually need a custom portal.

For example, Chicago Women in Philanthropy has a fairly sophisticated membership experience—accounts, event registration, invoices, directories, career-center access, etc.—while using membership software alongside its website. Chicago Women in Philanthropy Another Chicago nonprofit, Collaboraction, uses a separate online community ("The Co-Lab") for members. Collaboraction

An agency can potentially give you a much better result by integrating an existing membership/CRM platform than by building the whole thing from scratch.

My recommended RFP shortlist

If I were running your procurement, I'd invite 5 firms:

• Adage Technologies — technical/custom-platform benchmark
• Neoteric Design — custom product + nonprofit/arts
• Dialogue Theory — UX/design + mission
• Mightybytes — nonprofit + accessibility + digital product
• Three Hive Design — arts + membership/WordPress specialist

I'd also get a proposal from JCA if the portal is heavily tied to your CRM, fundraising, audience data or performing-arts operations. JCA is a Chicago nonprofit technology consultancy with 30+ years of nonprofit experience and explicitly works with performing-arts organizations. JCA

The key thing I'd ask each firm to price separately is (1) discovery/requirements, (2) UX/design, (3) portal development, (4) CRM/membership-platform integration, (5) data migration, (6) accessibility/security, and (7) 12 months of support. That will make the proposals much easier to compare.

If you tell me roughly how many members you have, your annual technology budget, what the portal needs to do (dues, member directory, event tickets, content, discounts, etc.), and what CRM/membership software you currently use, I can narrow this to 3 firms and give you a side-by-side assessment of likely fit, strengths, risks, and expected project cost.

Yes. For a Chicago arts nonprofit, I’d avoid treating this as a generic “website redesign.” A membership portal usually touches CRM/member records, payments, events, permissions, communications, accessibility, and the public-facing site. I’d shortlist firms with both arts/nonprofit experience and real portal/integration capability.

My shortlist

1. Adage Technologies — strongest overall candidate

Chicago-based and particularly interesting for a more complex portal. Adage has experience across arts, entertainment, music and nonprofits, including personalized/member portals and custom software. Current Chicago nonprofit rankings also specifically highlight its experience with personalized member portals. Clutch

Best if: you want a polished custom portal with substantial integrations and expect the system to grow.

2. Sandstorm Design — strong for a sophisticated arts/cultural organization

Sandstorm is Chicago-based and works with nonprofits and membership organizations, with capabilities spanning UX, web development, Drupal/WordPress and larger enterprise CMS implementations.

Best if: the portal needs to feel like an extension of a strong cultural/arts brand and accessibility/governance matter.

3. Dialogue Theory — strong design + UX option

This Chicago studio works specifically with mission-driven organizations and combines digital strategy, UX/UI and development.

Best if: member experience is the priority and you want the portal to be genuinely pleasant to use rather than just functional.

4. Three Hive Design — particularly worth an RFP

This is one of the most directly aligned matches I found: they explicitly build membership portals, community directories and volunteer-management platforms, and have an arts/cultural-institution practice. Three Hive Design

Best if: you're looking for a smaller, focused agency rather than a large enterprise shop.

5. Orbit Media Studios — excellent nonprofit/arts web partner

Orbit has an unusually strong Chicago nonprofit portfolio, including Goodman Theatre, Awakenings and other cultural/nonprofit organizations. Its work emphasizes UX, accessibility, content management and conversion-oriented nonprofit sites. Orbit Media Studios Orbit Media Studios

Best if: you're considering rebuilding the public website at the same time as the portal.

6. View Marketing & Creative — good nonprofit + membership experience

They have a Chicago nonprofit case study where they built a Webflow site and styled/integrated membership portals to create a seamless transition between the public site and member dashboard. View Marketing

Best if: you want a modern, visually strong nonprofit site with an existing membership system underneath it rather than a completely bespoke application.

One important alternative: don't necessarily build the portal from scratch

If by “membership portal” you mean things like member login, profile, dues/renewal, member benefits, event registration, member directory and communications, I'd seriously investigate an existing nonprofit/arts membership platform before commissioning custom software.

For example, Neon One, LLC is Chicago-based and its Neon CRM ecosystem includes memberships, renewals, member portals, events, fundraising, communications and payments.

For a performing-arts organization specifically, UpStage CRM is also unusually relevant: its platform is designed around performing-arts organizations and includes memberships, patron portals, ticketing, fundraising, events and digital tickets. UpStageCRM

And Cuseum is worth looking at if you're a museum/cultural attraction or have a significant visitor-membership program; it offers branded supporter portals, member benefits, CRM integrations and digital membership cards. Cuseum

How I'd approach the selection

I'd invite 4 firms to respond rather than sending an RFP to 15:

• Adage — complex/custom solution
• Three Hive — focused membership/community platform
• Sandstorm — larger cultural/institutional digital build
• Orbit or View — nonprofit/arts-oriented experience and UX

Then have each respond to the same requirements, particularly:

• Member registration, login and password recovery
• Individual vs. organizational memberships
• Multiple membership tiers
• Online dues/payment and automatic renewal
• Member profiles and directory
• Event registration
• Member-only content/resources
• Discount/benefit management
• Staff/admin dashboard
• CRM integration and data migration
• Email/marketing integration
• SSO, if applicable
• Accessibility/WCAG compliance
• Mobile experience
• Analytics
• Data ownership/export
• Ongoing maintenance and hosting
• Estimated implementation cost and 3-year total cost

I'd also ask them to distinguish what they would build custom vs. what they'd configure from an existing platform. That's probably the single most important question for keeping an arts nonprofit from spending $200K+ recreating functionality that already exists.

One particularly useful precedent: Chicago Loop Alliance's recent website/CRM RFP called for exactly this kind of combined system—member portal, billing/payments, events, member listings, fundraising, CRM/AMS integration and migration—rather than treating the website as a standalone project. Loop Chicago

If you tell me (1) your approximate membership size, (2) whether you already have a CRM/AMS, (3) whether you need dues/payment processing, and (4) your rough budget, I can narrow this to 3–5 firms and rank them by fit, likely cost, arts experience, and technical capability, including contact/website links.

Yes. For a Chicago-based arts nonprofit, I’d prioritize firms that understand both mission-driven digital work and membership infrastructure—not just agencies that make attractive nonprofit websites.

My shortlist

1. Venture Industries Online — best arts-specific fit
   • This is the first firm I’d contact.
   • They explicitly specialize in websites for arts organizations and artists and have worked with organizations including the League of Chicago Theatres and performing-arts organizations. Their League of Chicago Theatres project involved multiple complex sites serving member theatres, patrons, artists and administrators. ventureindustriesonline.com
   • Particularly compelling if your portal needs to connect membership, events, ticketing, content, and different user groups.

2. Mightybytes — best mission-driven digital/product partner
   • Chicago-based and focused specifically on mission-driven organizations.
   • Stronger candidate if this is a true custom portal/application, rather than simply a member-login area attached to a website. Their work includes product development, front- and back-end development, integrations, QA, training, hosting and ongoing support.
   • I'd put them high on the list if accessibility, sustainability, UX, and long-term maintainability matter.

3. Adage Technologies — best for a substantial custom build
   • Chicago software/digital firm with capabilities spanning strategy, UX, custom development, integrations and ongoing support.
   • I'd consider them if you're envisioning sophisticated functionality—member dashboards, profiles, payments, event registration, CRM integration, personalized content, etc.—rather than a conventional WordPress membership site.

4. Promet Source — best for complex nonprofit/association requirements
   • Chicago-based and particularly strong in Drupal, accessibility, security and organizations with complicated content/governance requirements.
   • Worth approaching if your nonprofit has a sizable membership, multiple permission levels, extensive archives/resources, or significant integrations.

5. Dialogue Theory — best UX/design-led option
   • A Chicago digital design/development studio focused on mission-driven organizations.
   • I'd include them if the portal needs to feel exceptionally polished and arts-oriented, rather than like a generic association-management system.

6. click5 Interactive LLC — good boutique/custom-development option
   • Chicago-based and does both websites and web applications, including WordPress and more complex application development.
   • Could be a good fit if you want a smaller team and more direct access to the people actually building the system.

One important distinction

I'd first decide whether you actually need a custom membership portal or a membership-management platform integrated into a redesigned website.

For example, Chicago organizations already use fairly sophisticated member systems. The Chicago Cultural Alliance has a member portal where organizations can log in, submit events, and access member resources. www.chicagoculturalalliance.org Chicago Women in Philanthropy's system supports accounts, event registration, invoices, profiles, career resources and member-only communications. members.cwiponline.org

If your requirements are things like:

• member signup/renewal
• recurring dues
• member profiles/directory
• event registration
• member-only content
• invoices/receipts
• automated emails
• staff administration
• CRM integration

…I would not automatically commission someone to build all of that from scratch. I'd ask the agencies to recommend whether to use something like a membership/CRM platform underneath the portal.

If, however, you want something more distinctive—e.g. artist profiles, portfolios, member networking, private archives, calls for artists, grant/program applications, member benefits, community forums, or sophisticated permissions—then a custom development partner becomes much more attractive. Chicago's Bridge/Artists United project is an interesting local example of this more elaborate model: it combines membership tiers, a searchable creative-worker directory, profiles, archives, benefits and other member resources. www.bridge-chicago.org

Who I'd invite to the RFP

I'd start with four rather than sending an RFP to 15 firms:

Then add Dialogue Theory if visual/UX quality is a major priority.

One caveat: I would not choose purely on portfolio aesthetics. For a membership portal, the crucial questions are what CRM/membership systems they've integrated, how they handle authentication and permissions, recurring payments, data migration, accessibility, security, and post-launch support.

If you tell me roughly (1) number of members, (2) current website/CMS, (3) current CRM or membership database, (4) desired portal features, and (5) budget range, I can narrow this to 3 firms and give you a side-by-side recommendation, including which one I'd hire.

• Mightybytes - 4001 N Ravenswood Ave, Ste 404, Chicago, IL 60613
• Dialogue Theory - 1932 S Halsted St #509, Chicago, IL 60608, United States
• Neoteric Design - 29 E Madison St, Ste 450, Chicago, IL 60602
• EDUCO Web Design - 128 Chicago Ave, Oak Park, IL 60302, United States
• Thirdwave - 15 W Hubbard St, Chicago, IL 60654, United States
• Cybernautic Web Design - 515 N State St #14-126, Chicago, IL 60611, United States
• NAV & Associates - 1018 W Madison St Ste 9, Chicago, IL 60607, United States
• Lipman-Hearne - 200 S Michigan Ave, Chicago, IL 60604
• Adage Technologies - 10 S Riverside Plaza Ste 1500, Chicago, IL 60606, United States
• Big Buzz Idea Group - 4055 W Peterson Ave #105, Chicago, IL 60646, United States
• Heller Consulting - 53 W Jackson Blvd, Ste 622, Chicago, IL 60604
• Chicago Association Management - 400 E Randolph St Apt 3115, Chicago, IL 60601, United States
• Advocate Creative - 320 N Damen Ave d301, Chicago, IL 60612, United States
• Smithbucklin - 330 N Wabash Ave #2000, Chicago, IL 60611, United States
• Artversion - 205 N Michigan Ave 8th Floor, Chicago, IL 60601
• David James Group - 1 Trans Am Plz, Oak Brook, IL 60523

Yes. For a Chicago arts nonprofit, I’d focus less on generic web-design shops and more on firms that understand membership workflows, nonprofit CRMs/AMSs, events, payments, gated content, and accessibility.

Based on current research, these are the firms I’d put on the first outreach list:

My shortlist

1. Mightybytes — strongest overall fit

• Chicago-based, mission-driven digital agency.
• Does product/web development, UX, accessibility, integrations, training, hosting, and ongoing support.
• Particularly attractive if the portal needs to be a real digital product rather than simply a members-only section of your website. Aero Design
• I'd definitely include them in an RFP.
• Dialogue Theory — best for UX + complex nonprofit experience

• Chicago studio focused on mission-driven organizations and complex digital experiences.
• Good candidate if the portal needs a sophisticated, contemporary arts/cultural experience rather than an off-the-shelf association site.
• Neoteric Design — best for custom technology

• Chicago digital product/software firm with an emphasis on usable, maintainable web applications.
• Particularly interesting because its past work includes arts/education nonprofit web projects.
• I'd consider them if you envision custom functionality, integrations, or a portal that may evolve substantially over time.
• 83/Creative — best specialist for membership portals

• This is one of the most directly relevant firms I found: they explicitly build member portals and web applications for nonprofits and associations, including CRM/AMS integrations, WordPress/Drupal development, UX, and content strategy. 83 Creative
• They advertise 20+ years of experience and 100+ projects.
• Even though they're not Chicago-based, I'd invite them to bid. For this particular project, specialization matters more than geography.
• EDUCO Web Design — good nonprofit + Drupal/WordPress option

• Chicago-area agency with 20+ years in nonprofit web design and experience with organizations including LISC Chicago, Chicago Loop Alliance, Women Employed and BUILD Chicago. Educo Web Design
• Worth considering if the portal will live alongside a substantial public-facing website.
• View Marketing & Creative — interesting arts/nonprofit design option

• Their Chicago nonprofit work specifically discusses membership portals, member directories, events and integrations, with an emphasis on making the portal feel visually continuous with the public website. View Marketing
• I'd put them on the list if brand/design and member experience are especially important.

Two more I'd investigate

• Thirdwave — Chicago web-development firm with experience across nonprofit and institutional organizations; potentially a good fit for a technically substantial portal.
• Cybernautic Web Design — Chicago agency that specifically describes building password-protected customer/employee portals with multi-user accounts and access levels.

One important alternative: don't necessarily build a portal from scratch

If by "membership portal" you mean something like:

Member logs in → sees profile → renews membership → pays dues → registers for events → accesses member-only content → updates preferences → receives communications

…I would first determine whether you actually need custom software.

There are specialized membership/association-management platforms that can provide much of this functionality, with the agency handling the website, UX, integrations and implementation. For example, JourneyCARE is specifically positioned as an all-in-one system for membership organizations, including website/CRM, communications, payments, automations, member portals, events and learning.

That's potentially much less risky for a nonprofit than commissioning an entirely custom membership database.

If this were my RFP

I'd probably invite 5 firms:

I'd then give all five the same requirements document and compare proposals on architecture, integration strategy, accessibility, staff usability, ongoing costs, and ownership—not just visual design.

A particularly important question for an arts nonprofit is what system currently owns your member data. If you're using something like Salesforce, Tessitura, PatronManager, Neon One, Bloomerang, Blackbaud, Fonteva, Personify, WildApricot, etc., the best agency may be the one with deep experience integrating that particular system.

If you tell me (1) your approximate budget, (2) current website/CMS, (3) current CRM or membership database, and (4) what you want members to be able to do inside the portal, I can narrow this to 3–5 firms that are genuinely well matched, including likely project-cost ranges and specific relevant case studies.

• Sandstorm Design - 4422 N Ravenswood Ave #50, Chicago, IL 60640, United States
• Maven Digital - 23 N Racine Ave, Chicago, IL 60607, United States
• Progressive Data Services - 2161 W Leland Ave, Chicago, IL 60625
• NAV & Associates - 1018 W Madison St Ste 9, Chicago, IL 60607, United States
• Big Buzz Idea Group - 4055 W Peterson Ave #105, Chicago, IL 60646, United States
• Heller Consulting - 53 W Jackson Blvd, Ste 622, Chicago, IL 60604
• Chicago Association Management - 400 E Randolph St Apt 3115, Chicago, IL 60601, United States
• Smithbucklin - 330 N Wabash Ave #2000, Chicago, IL 60611, United States
• GiveCentral - 2 North Riverside Plz, Ste 1350, Chicago, IL 60606
• Access Direct Nonprofit Marketing - 209 Des Plaines Ave, Forest Park, IL 60130, United States
• Technical Registration Experts, Inc. - 1932 S Halsted St #413, Chicago, IL 60608, United States
• Nonprofit Megaphone - 1230 W 34th St, Chicago, IL 60608, United States
• Beth Interactive Inc. - 4541 N Ravenswood Ave #303, Chicago, IL 60640, United States

Yes. For a Chicago-based arts nonprofit, I’d put together a shortlist that balances three things: membership/portal engineering, nonprofit experience, and sensitivity to arts/cultural audiences. I would not hire a general branding agency unless it can demonstrate that it has actually built authenticated member experiences.

My shortlist

1. Sandstorm Design — strongest Chicago agency to interview

Sandstorm is probably my first call if you want a polished, audience-centered experience rather than simply bolting a login onto your existing website. It is Chicago-based and has substantial Drupal/WordPress, UX research, accessibility, and nonprofit experience. Its portfolio includes nonprofit and association work, and Pantheon describes 15+ years of Drupal/WordPress development. Pantheon Directory Clutch

Best for: a sophisticated member portal + website redesign, especially if your audience experience and brand are important.

2. 83/Creative — strongest specialist for the actual membership problem

This is the one I'd make sure is in your RFP. Their stated specialty is membership organizations, and their services explicitly include member portals, web applications, CRM/AMS integrations, WordPress and Drupal. That's unusually close to your requirement. 83 Creative

Best for: a portal that involves member accounts, directories, renewals, permissions, events, integrations, etc.

3. Maven Digital — particularly interesting for an arts/mission-driven organization

Maven Digital is a Chicago digital product consultancy with a social-impact orientation and clients including the Chicago Community Trust, Boys & Girls Clubs of Chicago, Shedd Aquarium, Oxfam International and the University of Chicago.

Best for: a more strategic/custom digital product where the portal is part of a broader transformation of how members interact with the organization.

4. Eastern Standard — excellent nonprofit digital/UX option

Eastern Standard specializes in nonprofit digital experiences and works across UX research, design, WordPress, Drupal, analytics and integrations. They specifically discuss integrations with systems such as DonorPerfect, Donorbox, Classy and Blackbaud. Eastern Standard

Best for: an organization that needs the portal integrated into a broader fundraising, content and digital strategy.

5. Kanopi Studios — technical heavyweight worth including

Kanopi has substantial nonprofit experience in both WordPress and Drupal. Its nonprofit portfolio includes organizations such as PEN America and Humane World for Animals; it also cites a multisite solution supporting 150+ member sites. Kanopi Studios

Best for: a technically complex or high-traffic portal where scalability, CMS architecture and long-term maintenance matter.

6. View Marketing & Creative — especially worth considering because of the arts/nonprofit fit

Their Chicago work for Chicago Women in Philanthropy is particularly relevant: they describe styling a membership portal to match the organization's Webflow site, creating a seamless transition between the public website and member dashboard. View Marketing

Best for: a visually distinctive arts organization where the portal needs to feel like an extension of the brand rather than an ugly third-party application.

7. iTech4Web — technical/value-oriented option

Progressive Data Services is another local option if the project is more database/CRM-oriented, while iTech4Web specifically advertises Chicago-area Drupal/WordPress development and nonprofit work. iTech4Web

Best for: a technically focused build where budget and CMS expertise are more important than a big creative-agency experience.

If it were my RFP

I'd invite four firms rather than sending it to 10:

I'd use Eastern Standard or Kanopi as alternates if the portal is technically complex.

One important point: don't frame the RFP as "we need a new website with a membership section." If this is a real membership portal, ask agencies to architect the member system first—identity/authentication, membership tiers, renewals, payments, permissions, profiles, directories, event access, content access, CRM synchronization, reporting and accessibility—and then design the public website around it.

For an arts nonprofit, I'd also ask each firm to demonstrate one comparable authenticated/member experience, not just show you beautiful nonprofit websites. A gorgeous homepage is weak evidence that an agency can build a reliable membership system.

If you tell me (1) approximate membership count, (2) what members need to do inside the portal, (3) your current website/CMS, and (4) rough budget, I can narrow this to 2–3 firms and tell you exactly why I'd choose each one.

Yes. For a Chicago arts nonprofit, I’d avoid treating this as a generic “website redesign.” A membership portal usually touches CRM/data, payments, events, permissions, member communications, and the public-facing brand experience. Chicago organizations are already tackling it this way—for example, Chicago Loop Alliance’s RFP called for a combined website + CRM/association-management system with member portal, billing, events, donations, listings, and migration. loopchicago.com

My shortlist

1. Dialogue Theory — strongest agency-style candidate
Chicago-based digital design/development studio working with nonprofits and mission-driven organizations. I'd put them near the top if you want a beautiful, custom member experience rather than simply configuring an association-management platform.

2. Heller Consulting — strongest technology/CRM candidate
Particularly compelling if the portal needs to sit on top of Salesforce or another sophisticated nonprofit CRM, or if data migration/integration is a major concern. Their focus is nonprofit technology strategy, implementation, data, and organizational adoption.

3. NEW Marketing Solutions — strongest arts/culture specialist
This one is especially worth approaching because they're Chicago-based and specifically focused on arts and culture organizations, with experience around ticketing/Tessitura and digital strategy.

4. Lipman-Hearne — strong membership + nonprofit communications option
A good candidate if membership growth, fundraising, brand, communications, and the digital experience all need to be addressed together. Their positioning explicitly includes membership organizations and nonprofit/philanthropic work.

5. Smithbucklin — best if you need more than development
This is much larger than a typical web agency. They provide membership growth/engagement, marketing, technology and broader association-management capabilities. I'd consider them if your nonprofit wants a long-term operating partner, not merely someone to build the portal.

6. Chicago Association Management — worth considering for membership operations
More of an association-management partner than a pure software-development agency. Their services encompass membership, communications, website/digital work and operational support.

One non-Chicago firm I'd add

Sage70 is particularly interesting for an arts nonprofit. It's a nonprofit technology/data strategy consultancy whose stated sectors include Arts, Culture & Humanities, and it lists the Art Institute of Chicago among its client success stories. www.sage70.comwww.softr.io

Sage70

Also: don't assume you need a custom-built portal

Depending on what you mean by “membership portal,” you may get a better result by having an agency select and configure an existing platform rather than building everything from scratch.

For example, Cuseum is specifically built around cultural organizations and offers branded member portals, digital membership cards, member lifecycle tools and integrations with systems including Tessitura, Altru, Salesforce, Blackbaud, Neon CRM, Eventbrite and others. cuseum.com

Cuseum

And Softr has specifically positioned its platform for arts organizations, including member portals, CRM functionality, secure logins and integrations. www.softr.io

If I were running the RFP

I'd invite 4 firms to pitch:

Then I'd potentially add Cuseum as a platform alternative so you can compare “custom agency build” against “configure a purpose-built cultural membership platform.”

The key questions I'd put in the RFP are: What CRM should sit underneath this? How will payments and renewals work? Can members manage their own profiles? How will events/ticketing integrate? What happens to our existing member data? What staff/admin tools do we get? What will we own after launch? And what is the 3-year total cost—not just the initial build?

If you tell me (1) roughly how many members you have, (2) your current CRM/ticketing system, (3) what you want members to be able to do in the portal, and (4) a rough budget, I can narrow this to 3–5 firms and give you a much more opinionated recommendation, including which ones I would not bother contacting.

Yes. For a Chicago arts nonprofit, I’d prioritize firms that understand both mission-driven digital experiences and the underlying complexity of membership—accounts, dues, renewals, events, member directories, gated content, CRM integration, and payments.

My shortlist

1. Sandstorm Design — strongest overall fit
   • Chicago-based and focused on mission-driven organizations.
   • Particularly strong in UX, accessibility, Drupal/WordPress, and larger data-driven web platforms.
   • I’d put them near the top if the portal needs to be a polished, custom experience rather than simply configuring membership software. clutch.co

2. Adage Technologies — best for complex integrations
   • Chicago firm with substantial custom web/application-development capability.
   • Particularly interesting if the portal needs to connect a membership database/CRM, ecommerce, events, payments, or other existing systems.
   • They have nonprofit experience involving self-service account portals and ecommerce. clutch.co

3. Dialogue Theory — best for a sophisticated arts/cultural experience
   • Chicago digital design/development studio working with mission-driven organizations.
   • I'd consider them if brand, UX, storytelling and member experience are as important as the underlying technology.

4. click5 Interactive LLC — good mid-sized Chicago option
   • Does both web design and application development, including WordPress and web applications.
   • Worth talking to if you want a relatively hands-on team rather than a large enterprise agency.

5. TXI — for a genuinely custom product
   • Chicago-headquartered digital product consultancy specializing in custom software and experience-led products.
   • I'd consider them if you're envisioning something more ambitious than a conventional website/member portal—for example, a sophisticated digital community or bespoke member application. clutch.co

Two alternatives I'd investigate

Aluent Group is particularly interesting because it has an unusually direct membership-portal precedent: it helped implement the complex online membership system for The Morton Arboretum, including membership packages, multiple individuals, renewals, discounts and ecommerce integration. That's very close to the problem you're describing. aluent.com

View Marketing & Creative is worth a conversation if your priority is a beautiful, manageable nonprofit website with a membership portal integrated into the experience. It specifically describes building membership portals alongside a Webflow nonprofit site. www.view-marketing.com

One important distinction

I'd first decide whether you actually need an agency to build a portal from scratch.

If your requirements are things like:

• member login/profile
• membership levels
• dues and recurring payments
• renewals
• event registration
• member directory
• gated resources
• email integration
• basic CRM synchronization

...you may get a better result by having an agency select/configure/integrate an existing membership platform rather than commissioning custom software.

For example, Chicago-based Covey is specifically developing membership software for nonprofits and associations with member-only pages, document libraries, profiles, events, payments and migrations—but it is currently in private beta, so I wouldn't make it the primary solution for an imminent project. coveyhq.com

Who I'd invite to the first round

If I were running the RFP, I'd probably invite Sandstorm, Adage, Dialogue Theory, Aluent, and one smaller shop such as click5. That gives you five meaningfully different approaches rather than five interchangeable web-design agencies.

And I would make the RFP ask each firm to show 2–3 actual membership/portal projects, identify the underlying platform/CRM, explain what was custom-built versus configured, and provide a rough total cost of ownership for 3 years, not just the initial build price.

If you tell me roughly your membership size, annual budget, existing website/CRM (e.g. WordPress, Salesforce, Tessitura, Spektrix, PatronManager, etc.), and what you want members to do inside the portal, I can narrow this to 3–5 firms and compare their likely fit, project cost, and relevant arts/nonprofit experience.

For a Chicago arts nonprofit, I’d look for a firm that understands membership economics, cultural audiences, donations/ticketing/events, accessibility, and integrations—not just a general web designer. A membership portal usually touches CRM, payments, content permissions, events, email, and data migration.

Here are firms I’d put on your shortlist:

Strong fits for a custom membership portal / digital platform

Mightybytes

A good candidate if you want a mission-driven digital partner rather than a purely technical shop. They focus on purpose-driven organizations and handle digital product strategy, development, accessibility, and ongoing support.

Ask them about:

• member dashboards
• integrations with your CRM/ticketing/donation systems
• accessibility (WCAG)
• long-term maintenance model

LaunchPad Lab

Worth approaching if you need a more custom application rather than a templated membership site. They explicitly work with nonprofits and social-impact organizations on custom digital tools. launchpadlab.com

Best fit if you need:

• custom member workflows
• complex permissions
• integrations with internal systems
• a portal that could evolve into a broader platform

Promet Source

A strong option for larger nonprofits that need robust CMS and open-source solutions (especially Drupal). They have experience with complex, multi-stakeholder digital platforms.

Best fit if you have:

• many member types
• institutional partners
• extensive content libraries
• governance requirements

Strong arts/nonprofit design + membership experience

LimeRed Studio

A mission-oriented Chicago studio with experience in branding, UX, websites, accessibility, and integrations. They may be a good fit if the portal needs to feel highly aligned with your artistic identity.

Best fit if you care about:

• beautiful member experience
• storytelling
• audience engagement
• balancing design with functionality

Dialogue Theory

A smaller, high-touch digital studio that focuses on UX, design, and development for mission-driven organizations.

Best fit if you want:

• close collaboration
• a thoughtful UX process
• a boutique partner

If you may not need a fully custom build

Before commissioning custom software, I’d also evaluate whether a strong membership platform plus a custom front end would solve your needs. Chicago nonprofits and associations often use combinations of CRM + membership tools + websites rather than building everything from scratch. For example, Chicago organizations have pursued systems combining websites, CRM, association management, events, payments, and member portals. loopchicago.com

Possible approaches:

• Website + membership platform integration (lower cost, faster)
• CRM/association management system customization
• Fully custom portal (highest flexibility, highest cost)

My suggested first outreach list (5 firms)

If I were issuing an RFP, I’d invite:

1. Mightybytes — mission alignment + digital product experience
2. LaunchPad Lab — custom portal capability
3. LimeRed Studio — arts/culture-friendly UX and design
4. Dialogue Theory — boutique collaboration
5. Promet Source — enterprise-grade CMS/platform work

I’d also consider a specialized membership/association technology consultant if your portal is primarily about renewals, member tiers, benefits, directories, events, and communications rather than a unique software product. Chicago has firms such as NAV & Associates that focus on membership operations and digital engagement strategy.

For an arts nonprofit, I’d include in your RFP:

• number of members and membership tiers
• whether members need profiles/directories
• event/ticketing integration needs
• donation integration
• restricted content/library needs
• accessibility requirements
• current CRM (e.g., Salesforce, Blackbaud, Neon, Bloomerang, Tessitura, etc.)
• budget range and desired launch date

That information will dramatically change which firms are the best fit.

Yes. For a Chicago-based arts nonprofit, I’d approach a fairly targeted shortlist rather than a generic web-design shop. A membership portal usually involves some combination of authentication, member profiles, dues/payments, event registration, gated content, CRM integration, permissions, and staff administration—so you want proven membership + nonprofit + digital product experience.

My shortlist

1. Adage Technologies — Best for a substantial custom portal
   • Chicago-based and technically strong in custom web applications and integrations.
   • Particularly interesting if the portal needs sophisticated account management, payments, databases, or integrations rather than simply styling an existing membership platform.
   • Clutch currently lists Adage at 5.0 and specifically notes its experience in the arts and nonprofit sectors. clutch.co
   • Ask them: Can you show us a comparable member portal, not just a nonprofit website?

2. Dialogue Theory — Best for UX + mission-driven digital experience
   • Chicago studio focused on digital strategy, UX/UI and web development for mission-driven organizations.
   • I'd put them high on the list if the portal needs to be genuinely pleasant for artists, members, donors, staff, etc., rather than merely functional.
   • Their work is explicitly oriented toward complex nonprofit/civic digital experiences.

3. Sandstorm Design — Best for a larger, more complex organization
   • Chicago-based, UX-driven agency with experience in enterprise web development, accessibility and data-driven applications.
   • Particularly worth considering if your nonprofit has a sizable existing website/CRM ecosystem or expects the portal to become a significant digital platform.
   • They work extensively with Drupal/WordPress and emphasize inclusive design.

4. click5 Interactive LLC — Good middle-market custom-development option
   • Chicago-based "creative technologists" doing both WordPress and web-application development.
   • Worth talking to if you need something more customized than a conventional nonprofit website but don't want an enormous enterprise engagement.

5. Bark Design — Especially interesting for arts/culture
   • This is one I'd put on the list specifically because Bark says it works with museums, education, technology, the arts and healthcare, in addition to mission-driven organizations.
   • It combines visual/brand work with UX, CMS, intranet and web development, which could be useful if the member experience needs to feel highly tailored to your arts organization.

6. LimeRed Studio, Inc. — Good mission/brand/UX choice
   • Chicago agency focused on purpose-driven organizations, with a strong nonprofit orientation.
   • I'd consider them if the portal is part of a broader digital/brand redesign rather than a standalone software project.

One firm I'd definitely interview: Orbit Media

Orbit Media Studios is particularly compelling for an arts nonprofit. They have a dedicated nonprofit practice and publicly cite work with Goodman Theatre, the Greater Chicago Food Depository, Erikson Institute and other nonprofits. Their Goodman Theatre case study reports a 55% increase in conversions. www.orbitmedia.com

They also explicitly discuss integrating websites with CRMs, databases and third-party systems rather than treating the website as an isolated marketing property. www.orbitmedia.com

Caveat: I'd want Orbit to demonstrate that they can own the portal/application portion of your project—not just the public-facing website.

An intriguing specialist option: View Marketing & Creative

View has a particularly relevant Chicago nonprofit case study: Chicago Women in Philanthropy. They redesigned the site's UX while integrating its existing membership software, including making the member experience visually cohesive with the main site. They specifically discuss integrations with MemberClicks, WildApricot, YourMembership and similar platforms. www.view-marketing.com

That's potentially a much better model if your organization doesn't actually need custom membership software and instead needs a beautifully designed front end around an existing membership system.

How I'd narrow it down

I'd issue an RFP/interview with 5 firms, probably:

Then add View if you're considering an existing membership platform rather than building the portal from scratch.

One important distinction: don't ask agencies simply for "a membership portal." Give them a list of required member journeys—e.g. join → pay dues → create profile → access member-only content → register for event → renew → update payment → staff manages membership—and ask each firm to propose the architecture. That will quickly reveal who actually understands the problem.

If you tell me your approximate budget (e.g. $50k, $100k, $250k+), number of members, existing CRM/membership software, and what the portal needs to do, I can narrow this to 3 firms I'd actually invite to bid, including likely project fit and questions to ask each.

Yes. For a Chicago-based arts nonprofit, I’d build the shortlist around firms that have demonstrated experience in arts/culture + nonprofit work + membership/portal functionality, rather than hiring a generic web-design shop.

My shortlist

1. Venture Industries Online — strongest arts-sector fit
   • This would be one of my first calls.
   • They specifically build websites for arts organizations and artists, and their portfolio includes the League of Chicago Theatres. That project involved multiple complex sites serving member theatres, patrons, artists, and administrators. ventureindustriesonline.com
   • Particularly attractive if your portal needs to feel arts-specific and beautifully designed, rather than like a generic association-management system.
   • Venture Industries Online

2. Sandstorm Design — best for a sophisticated UX/platform
   • Chicago-based, women-led agency with a strong emphasis on UX, inclusive design, and enterprise web development for mission-driven organizations.
   • I'd put them high on the list if the portal involves complicated member journeys, multiple audiences, integrations, accessibility requirements, or a substantial redesign alongside the portal.
   • Sandstorm Design

3. Orbit Media Studios — excellent nonprofit + membership experience
   • Orbit has substantial Chicago nonprofit experience. Its work for Awakenings, a Chicago arts/healing nonprofit, included strategy, UX, design, development, accessibility, events, and conversion journeys. www.orbitmedia.com
   • More importantly for you, Orbit also built the site for The Executives' Club of Chicago, with explicit goals around attracting members, showcasing events, and serving existing members. www.orbitmedia.com
   • That's a particularly relevant combination of nonprofit + membership + events + Chicago.
   • Orbit Media Studios

4. View Marketing & Creative — particularly strong if you're integrating existing membership software
   • Their Chicago Women in Philanthropy project is unusually relevant: the organization already had membership software, and View redesigned the public site and coordinated the membership-software experience so the portal felt like one cohesive website. www.view-marketing.com
   • They specifically discuss integrations with MemberClicks, WildApricot, YourMembership, etc.
   • I'd move them toward the top if you already have a membership database/platform and don't necessarily want to replace it.
   • View Marketing & Creative

5. Design In Chicago — good candidate for a genuinely custom portal
   • Their capabilities specifically include portal/dashboard development, intranet portals, CRM integration, LMS development, web applications, and custom digital products.
   • I'd investigate them if by "membership portal" you mean more than gated content—for example, member profiles, directories, applications, payments, dashboards, resources, events, or custom workflows.
   • Design In Chicago

6. Mightybytes — strong mission-driven/strategy option
   • Chicago-based and deeply experienced with nonprofits. Their work with Chicago Community Trust included digital strategy, accessibility, website work, and improving the user experience of a major registration system. ventureindustriesonline.comwww.mightybytes.comwww.tecture.com
   • I'd consider them particularly if the portal is part of a larger digital transformation, rather than simply a website build.
   • Mightybytes

One wildcard I'd interview

Tecture is worth considering if the portal is really a custom software application rather than a website with member login. They're Chicago-based and explicitly develop custom web applications for nonprofits, including WordPress integrations and custom software. www.tecture.com

Tecture

How I'd narrow it

I'd probably issue an RFP to 4 firms:

Then add Design In Chicago or Tecture if you anticipate substantial custom application development.

The biggest question before selecting an agency is what you mean by "membership portal." A portal with login + gated resources is a very different project from one with membership applications + dues + profiles + directory + events + ticketing + CRM integration + personalized dashboards.

If you give me (1) your approximate budget, (2) number/type of members, (3) what the portal needs to do, and (4) what system you currently use for CRM/membership/ticketing, I can turn this into a ranked 5–7 firm shortlist with estimated project-fit, likely budget tier, relevant case studies, and who I'd contact first.

For a Chicago-based arts nonprofit, I’d look beyond generic web shops and prioritize agencies that understand membership ecosystems: CRM integration, dues/subscriptions, events, ticketing, donor/member journeys, accessibility, and arts-sector audiences. A good shortlist to approach:

How I’d narrow the list

For an arts nonprofit, I’d probably invite 4 firms to an RFP/discovery conversation:

1. Venture Industries Online — if your priority is arts-sector understanding. ventureindustriesonline.com
2. Adage Technologies — if the portal will involve serious integrations (CRM, ticketing, databases, permissions). clutch.co
3. Orbit Media Studios — if you need strong nonprofit UX, storytelling, accessibility, and maintainability. www.orbitmedia.comwww.orbitmedia.com
4. Sandstorm Design or Spry Digital — if you expect a larger custom platform build. clutch.co

Questions I’d ask every agency

• Have you built member portals, not just nonprofit websites?
• Which membership/CRM platforms have you integrated with? (e.g., Salesforce, Neon One, Blackbaud, Fonteva, MemberClicks, WordPress membership tools)
• Can members:
  • renew dues?
  • update profiles?
  • access benefits/resources?
  • register for events?
  • receive segmented communications?
• How will you handle accessibility (WCAG), especially for arts audiences?
• Who owns the code, hosting, and integrations after launch?
• What ongoing support model do you offer?

A rough budget expectation: a serious custom membership portal for a nonprofit often lands anywhere from $40k–$150k+, depending on integrations, design complexity, data migration, and whether it is a portal layered onto an existing website or a full platform rebuild.

If you share your membership size, current website/CMS, CRM or ticketing system, and desired portal features, I can help narrow this to the 3–5 firms most likely to fit.

Yes. For a Chicago-based arts nonprofit, I’d prioritize firms that can handle more than a marketing website: member accounts, payments/renewals, events, directories, permissions, CRM/AMS integrations, and a staff-admin experience.

My shortlist

1. Adage Technologies — strongest candidate for a complex portal
   • Chicago-based and experienced with custom software and digital platforms.
   • Particularly interesting if you need a genuinely custom member portal rather than simply styling an off-the-shelf membership system.
   • They have experience with self-service account portals and nonprofit digital projects.
   • Best for: sophisticated integrations, custom workflows, CRM/ERP connectivity, larger-scale builds.

2. Thirdwave — excellent for complex nonprofit/member ecosystems
   • Chicago web-development firm with full-stack capabilities.
   • Their work includes consolidating multiple systems into a portal environment, with migration, training, calendars and custom applications.
   • Best for: an organization whose membership portal needs to connect to several existing systems. loopchicago.com

3. Sandstorm Design — strong UX/accessibility choice
   • Chicago agency with substantial experience in mission-driven organizations, UX, accessibility and enterprise web development.
   • A good fit if the portal needs to serve a diverse arts audience and you care deeply about usability and accessibility.
   • Best for: member experience + accessible design + robust CMS.

4. Dialogue Theory — worth interviewing for a highly user-centered portal
   • Chicago digital design/development studio focused on mission-driven organizations and complex digital experiences.
   • I'd put them on the list if the project involves significant discovery, UX research, or rethinking how members interact with the organization.
   • Best for: designing a great member experience rather than simply implementing software.

5. Design In Chicago — interesting mid-sized option
   • Their capabilities specifically include portal/dashboard development, intranet portals, CRM integration and web applications, alongside conventional web design.
   • Best for: a portal that needs custom functionality but doesn't necessarily require a huge enterprise implementation.

6. Mightybytes — particularly good mission fit
   • Chicago-based and focused on mission-driven organizations, with web/product development, accessibility, training and ongoing support.
   • I'd seriously consider them if sustainability, accessibility and nonprofit culture are important selection criteria.
   • Best for: mission alignment + thoughtful digital product development.

One more option if your membership system is the real problem

Heller Consulting is worth considering as a technology/CRM strategy partner, particularly if you're unsure what your underlying membership/CRM architecture should be. They specialize in nonprofit technology, CRM implementations, data migration and organizational adoption.

That distinction matters. Don't hire a web-design agency first if the real project is replacing an association-management system. A good firm should help you decide whether to build a portal around something like Salesforce, a dedicated AMS, WordPress/Drupal, or a custom application.

I'd approach these four first

If I were running your RFP, my initial outreach would be:

There is also a useful Chicago precedent: the Chicago Loop Alliance's recent website/CRM RFP explicitly called for integrating a member portal, billing/payments, event registration, member listings, applications, fundraising and CRM/association-management systems. That is very close to the architecture I'd expect an arts nonprofit to need. loopchicago.com

And Chicago arts organizations are already using fairly sophisticated membership experiences—for example, the Chicago Cultural Alliance has a member portal with authenticated accounts and member resources, while Chicago Women in Philanthropy combines accounts, events, invoices, profiles, a directory and members-only benefits. www.chicagoculturalalliance.org

My recommendation: don't ask these firms simply for a "membership website." Ask for a member-experience and technology architecture engagement, followed by implementation. That framing will produce much better proposals.

If you tell me roughly (a) number of members, (b) current CRM/membership software, (c) what members need to do inside the portal, and (d) your approximate budget, I can narrow this to 3 firms and give you a suggested RFP/brief and questions to use in the agency interviews.

Yes. For a Chicago arts nonprofit, I’d avoid treating this as a generic website project. A good membership portal usually involves member accounts, dues/renewals, event registration, gated content, CRM integration, email automation, payments, and staff administration—so you want a firm that understands both arts audiences and the underlying technology.

I’d put these firms on your initial shortlist:

1. Adage Technologies — strongest for a complex/custom portal

Adage Technologies
Web
Address: 10 S Riverside Plaza Ste 1500, Chicago, IL 60606, United States
Phone: +1 312-258-1200
Adage is probably my first call if the portal is more than a relatively simple member login. They combine strategy, UX, and custom software development and have experience with associations and cultural institutions. Their portfolio includes work for the American Academy of Pediatrics and The Met, including sophisticated account/e-commerce experiences. adagetech.com

Adage Technologies

Best for: custom member dashboards, integrations, complex databases/CRM, unusual workflows, scalability.

2. Dialogue Theory — strong UX + mission-driven fit

Dialogue Theory
Web
Address: 1932 S Halsted St #509, Chicago, IL 60608, United States
Phone: +1 617-922-3790
This Chicago studio focuses on digital strategy, UX/UI, and development for mission-driven organizations. I'd consider them particularly if the member experience itself is the priority rather than simply getting an existing membership system connected to your website.

Best for: an elegant, highly usable portal; organizations that need discovery/research and custom UX.

3. IDE Interactive, Inc. — strong custom-product option

IDE Interactive, Inc.
Web
Address: 2945 W Peterson Ave Ste 103, Chicago, IL 60659, United States
Phone: +1 312-877-6154
IDE is another interesting candidate if you're effectively building a digital product, not just a website. They explicitly build web applications, portals and custom software, and describe their approach as user-centered strategy + design + development. adagetech.comwww.ideinteractive.com

IDE Interactive

Best for: custom member portals, complicated workflows, integrations, dashboards, or eventually turning the portal into a broader digital platform.

4. Nicer Collaborative: A Creative Studio — particularly interesting for arts/culture

Nicer Collaborative: A Creative Studio
Web
Address: 1361 N Ashland Ave Storefront, Chicago, IL 60622, United States
Phone: +1 312-972-4009
This is a smaller Chicago creative studio that combines branding, UX, web development and web applications. Its work appears particularly compatible with arts/culture and event-driven organizations, including workflows involving calendars, ticketing, membership and e-commerce.

Best for: a smaller, hands-on team where the portal needs to feel beautiful and closely integrated with the organization's brand.

5. Sandstorm Design — strong design/accessibility candidate

Sandstorm Design
Web
Address: 4422 N Ravenswood Ave #50, Chicago, IL 60640, United States
Phone: +1 773-348-4200
Sandstorm is a Chicago digital agency with a focus on UX, inclusive design, accessibility and enterprise web development. I'd put them on the list if the portal needs to serve a broad, diverse membership and accessibility is an important requirement.

Best for: UX research, accessibility, content strategy, complex institutional websites.

6. Venture Industries Online — the arts-specific wildcard

This one deserves special attention. Venture Industries Online is explicitly built around arts organizations and artists, rather than simply having nonprofits somewhere in its portfolio. It has worked with the League of Chicago Theatres, and its arts clients include opera companies, theaters, orchestras and museums. ventureindustriesonline.com

It also offers event management, email marketing, CRM integration, custom programming and member/password-protected functionality. ventureindustriesonline.com

Best for: an arts organization that wants an experienced arts-tech partner rather than a general-purpose digital agency.

7. Heller Consulting — if CRM/data is the hard part

Heller Consulting
Web
Address: 53 W Jackson Blvd, Ste 622, Chicago, IL 60604
Phone: +12242417489
I'd consider Heller if the portal is really part of a larger CRM/member-data transformation. They specialize in technology consulting for nonprofits and social-sector organizations, including CRM implementations and Salesforce/Blackbaud ecosystems.

Best for: Salesforce/CRM, data migration, systems architecture, integrations and organizational change—not primarily visual design.

My recommended shortlist

If I were running your procurement process, I'd invite four firms to discovery calls:

I'd add Heller if CRM/data integration is substantial, and Sandstorm if accessibility and UX research are major requirements.

One useful benchmark: Chicago Loop Alliance's recent website/CRM RFP is surprisingly close to the kind of problem you're describing—it called for integrating membership, event registration, fundraising, member billing/payments, member listings, applications, CRM/AMS and the website, rather than treating the portal as an isolated website. loopchicago.com That's the level of systems thinking I'd look for in your agency selection.

One important procurement recommendation

Before approaching agencies, I'd make them respond to the same 2–3 page brief describing:

• current website/CMS
• current membership database/AMS/CRM
• number and types of members
• dues/renewal model
• events/ticketing
• member directory
• gated content/resources
• payments
• email/marketing automation
• staff/admin workflows
• accessibility requirements
• integrations you already have
• what you want members to be able to do after logging in
• approximate budget and desired launch date

Then ask each agency to recommend the technology stack, rather than specifying one yourself. That will expose whether you're actually buying a custom portal—or whether an existing AMS/member platform with a beautifully integrated front end would accomplish the job for substantially less.

If you tell me your approximate membership size, current CRM/membership system, and budget (e.g. $25–50k, $50–100k, $100k+), I can narrow this to 3–5 firms and compare them on arts experience, portal capability, likely budget tier, technology approach, and relevant past projects.

Yes. For a Chicago arts nonprofit, I’d prioritize firms that understand both arts/culture audiences and the unusually tricky combination of membership, events, payments, CRM, and authenticated member experiences.

My shortlist

1. Adage Technologies — strongest technical/custom-portal candidate
   • Chicago-based and substantially more engineering-oriented than a typical creative agency.
   • Particularly interesting if you want a true member portal rather than simply a redesigned website with a membership plug-in.
   • Their nonprofit work includes a self-service “My Account” portal and integrations, which is relevant to your requirements. loopchicago.com
   • I'd approach them if: you need custom workflows, integrations, sophisticated account management, or expect the portal to become a significant digital product.

2. Dialogue Theory — strong UX + mission-driven digital partner
   • Chicago studio focused on digital strategy, UX/UI and web development for mission-driven organizations.
   • I'd put them on the RFP list if the portal needs to feel beautiful, intuitive and aligned with an arts organization's brand, rather than like a generic association-management system.

3. Venture Industries Online — particularly compelling for arts organizations
   • This is the most obvious arts-sector specialist I found.
   • They explicitly work with arts organizations and artists, and cite projects for the League of Chicago Theatres, Lyric Opera, and Racine Theatre Guild. The League of Chicago Theatres testimonial specifically describes a complex overhaul serving member theatres, patrons, artists and administrators. ventureindustriesonline.com
   • I'd definitely include them in the first round.
   • Venture Industries Online

4. Sandstorm Design — excellent if accessibility and UX are priorities
   • Chicago-based, women-led agency with emphasis on UX, inclusive design and enterprise web development.
   • Their experience with data-driven applications and CMS platforms makes them worth considering for a more sophisticated portal.
   • I'd approach them if: accessibility, user research, information architecture and a polished member experience are major priorities.

5. Orbit Media Studios — strong nonprofit + Chicago track record
   • Their nonprofit portfolio includes Goodman Theatre, with a reported 55% increase in conversions, as well as Alliance Theatre and other nonprofits. www.orbitmedia.com
   • Their focus appears somewhat more website/content/strategy-oriented than portal-engineering-oriented, so I'd ask specifically about their experience with authenticated membership systems.
   • Orbit Media Studios

6. View Marketing & Creative — good fit for a smaller/mid-sized organization
   • They have unusually relevant Chicago nonprofit membership experience: they built the website for Chicago Women in Philanthropy and coordinated the integration and styling of its existing membership software. www.view-marketing.com
   • This is a good choice if you don't necessarily need to build the membership engine from scratch and instead want a beautifully branded website + seamless member experience around an existing platform.

One important distinction

I'd first decide whether you actually need a custom membership portal.

There are roughly three approaches:

For an arts nonprofit, the portal might eventually need things like member profiles, renewal/payment, event registration, member-only resources, artist/theatre directories, discounts, committees, newsletters, ticketing integration, CRM synchronization and different permission levels. Chicago organizations are already dealing with this level of complexity—for example, Chicago Loop Alliance's recent technology requirements called for member information, events, payments, donations, QuickBooks integration, CRM synchronization and ADA accessibility. loopchicago.com

If it were my RFP

I'd invite 5 firms to a first conversation:

Adage Technologies · Venture Industries Online · Dialogue Theory · Sandstorm Design · Orbit Media Studios

And I'd use View Marketing as a sixth/benchmark proposal if you're considering an existing membership platform rather than building the whole thing.

I would not start with a generic nonprofit web-design shop just because they have a nice portfolio. A membership portal is fundamentally a product/UX/integration project, and the ability to make a pretty homepage is a different skill.

If you tell me roughly (a) your annual budget, (b) number of members, (c) what the portal needs to do, and (d) what CRM/membership/ticketing system you currently use, I can narrow this to 3 firms and tell you exactly what I would ask each one in the RFP.

Yes. For a Chicago arts nonprofit, I’d build a shortlist around firms that understand both mission-driven digital experiences and the less glamorous parts of membership: member records, renewals, payments, events, permissions, CRM integrations, and staff administration.

My first calls

1. Adage Technologies — strongest choice for a genuinely custom portal
   • Chicago-based software/web development firm with substantial custom application capability.
   • Particularly interesting for you because Clutch specifically highlights Adage’s arts and nonprofit-sector expertise and custom web/application development. clutch.co
   • I’d put them at the top if the portal needs sophisticated member accounts, integrations, complex permissions, or a custom backend.
   • Adage Technologies

2. Sandstorm Design — strongest UX/accessibility-oriented option
   • Chicago agency with deep experience in mission-driven organizations, UX, inclusive design and enterprise web development. clutch.co
   • Good candidate if the portal needs to feel beautiful and arts-oriented, rather than like a generic association-management system.
   • Their technical capabilities include data-driven applications and platforms such as Drupal and WordPress.
   • Sandstorm Design

3. Orbit Media Studios — particularly compelling for an arts/cultural organization
   • This is probably the best "arts nonprofit + website + member experience" conversation I'd have.
   • Orbit has worked with Goodman Theatre and other nonprofits, and specifically discusses custom integrations, event registration, resource libraries, accessibility and UX. Goodman Theatre's testimonial says Orbit helped represent it as a "world-class cultural institution." www.orbitmedia.com
   • They also have a substantial Chicago nonprofit track record. clutch.cowww.orbitmedia.comwww.dialoguetheory.com
   • Orbit Media Studios

4. Dialogue Theory — boutique option I'd seriously consider
   • Smaller Chicago studio focused on complex digital experiences for nonprofits and civic organizations. Their positioning is explicitly about combining strategy, UX, design and technology rather than simply building a website. www.dialoguetheory.com
   • Could be an excellent fit if you want a high-touch, highly customized member experience rather than a big-agency process.
   • Dialogue Theory

5. View Marketing & Creative — worth a conversation if the portal is relatively straightforward
   • They have unusually relevant evidence: their work for Chicago Women in Philanthropy included styling a membership portal to match the organization's Webflow site, with member dashboards and CMS functionality. www.view-marketing.comwww.chicagoculturalalliance.orgloopchicago.com
   • I'd investigate them if you're envisioning something like member login, profile management, directory, events/resources and payments rather than a deeply custom software application.
   • View Marketing & Creative

One important distinction

I'd first determine whether you actually need an agency-built membership portal or whether you need an existing membership/association platform customized and integrated with your website.

For example, Chicago's own membership ecosystem includes organizations using systems such as Neon CRM, and there are platforms that already provide member portals, renewals, events, payments and directories. www.chicagoculturalalliance.org

If your requirements are mostly:

• member login/profile
• membership levels and renewals
• dues/payment processing
• member directory
• event registration
• private resources
• email communications
• staff/admin dashboard

…I would not automatically commission a custom application. You could spend substantially more than necessary.

If instead you need things like:

• complicated membership eligibility
• multiple classes of artists/members
• custom benefits/entitlements
• member-generated content
• artist portfolios
• sophisticated permissions
• integration with ticketing, CRM, accounting or donor systems
• unusual renewal/payment rules
• a highly distinctive cultural-sector UX

…then Adage, Sandstorm, Orbit or Dialogue Theory become much more compelling.

How I'd run the selection

I'd invite 4 firms to respond to the same short RFP:

I'd then ask each one to provide a fixed-price discovery phase, rather than immediately asking for a full build quote. That discovery should produce the recommended platform/architecture, member journey, integrations, data model, accessibility requirements, implementation cost and ongoing maintenance cost.

One particularly useful benchmark: a recent Chicago Loop Alliance RFP described a very similar problem—website plus CRM/association-management functionality, member/donor/event management, communications and payment processing—so your RFP should explicitly cover those areas rather than simply saying "membership portal." loopchicago.com

If you tell me roughly how many members you have, what your current website/CRM/ticketing system is, and what you want members to be able to do inside the portal, I can narrow this to 3 firms and give you a recommended RFP scope and budget range.

Yes. For a Chicago arts nonprofit, I’d prioritize firms that understand both membership/CRM infrastructure and the front-end member experience, rather than hiring a generic web-design shop.

My shortlist

1. Promet Source — strongest choice for a complex portal
   • Chicago-based, with deep nonprofit/association experience.
   • Particularly strong if you need a secure, accessible portal with sophisticated permissions, integrations, content management, and custom workflows.
   • Drupal/WordPress expertise is useful if the portal needs to live alongside an existing institutional website.
   • I’d put them on the RFP list if this is a substantial technology project. loopchicago.com

2. Giant Rabbit — strongest arts/nonprofit specialist
   • This is probably the most directly relevant firm I found. They explicitly specialize in arts & culture organizations and have worked on membership, donation, ecommerce, CRM, and website integrations for museums and other arts organizations.
   • They say they've served 300+ nonprofits and specifically cite integrating membership systems with websites, stores, accounting, events and CRM systems. giantrabbit.comyab.dev
   • Giant Rabbit

3. Yab — best if you need a genuinely custom member portal
   • Their arts/culture practice is unusually specific: they build donor and member portals, integrate with Spektrix and Tessitura, and connect those systems to donor CRMs and websites.
   • Their examples include member self-service, renewals, ticket access, giving history and benefit lookup. yab.dev
   • This would be one of my first calls if you're a performing-arts organization or use Tessitura/Spektrix.
   • Yab

4. Sandstorm Design — best for UX + sophisticated website
   • Chicago agency with a strong UX/design orientation and experience with mission-driven organizations.
   • Worth considering if the portal needs to feel exceptionally polished and accessible, rather than being primarily an administrative/member-management system.

5. Dialogue Theory — good boutique option
   • Chicago-based digital design/development studio focused on mission-driven organizations.
   • I'd consider them for a smaller, more design-led portal where you want senior attention rather than a large agency team.

6. Maven Digital — interesting nonprofit-focused alternative
   • Chicago digital-product consultancy with a nonprofit/social-impact orientation and clients including Shedd Aquarium, Chicago Community Trust and other major mission-driven organizations.
   • Worth an exploratory conversation if the portal involves broader digital-product strategy rather than simply website development.

One important distinction

Before choosing an agency, I'd decide whether you actually need a custom membership portal or a membership platform with a branded front end.

For example, Cuseum has a purpose-built branded member/supporter portal for cultural organizations, including member benefits, account management, digital membership cards and integrations with systems such as Tessitura, Altru, Salesforce and Neon CRM. cuseum.com

Likewise, Neon One is worth evaluating if your underlying problem is really membership + donor CRM + events rather than custom software. It specifically markets an integrated solution for arts/culture organizations and has Chicago arts clients. neonone.com

Who I'd actually invite to the first round

If I were running your procurement, I'd send an RFP to:

Giant Rabbit + Yab + Promet Source + Sandstorm Design

That gives you four quite different approaches:

I'd also ask Cuseum and Neon One for demos—not necessarily as agency bidders, but to establish whether buying/configuring an existing platform could accomplish 70–90% of what you're envisioning for substantially less money.

One useful signal: a recent Chicago Loop Alliance RFP described almost exactly this kind of problem—website + CRM + association/membership management + donor tracking + events + communications + payments—which suggests the local market has relevant experience with this combination. loopchicago.com

If you tell me (1) your approximate membership size, (2) what CRM/ticketing system you use now, (3) what you want members to do inside the portal, and (4) rough budget ($50k / $100k / $250k+), I can narrow this to 3 agencies I'd interview and explain exactly why, including relevant arts clients and comparable projects.
